docs(features2d): document getBlobContours and collectContours in SimpleBlobDetector #28275

Description: This PR adds missing Doxygen documentation for the getBlobContours() method and the collectContours parameter in SimpleBlobDetector. These features were previously undocumented, making the contour collection functionality difficult for users to discover and use correctly.

Changes:
Added a @brief and detailed note for SimpleBlobDetector::Params::collectContours.
Added documentation for SimpleBlobDetector::getBlobContours(), including a @note regarding the required parameter setup.

Testing:
Verified the documentation build locally on macOS using ninja opencv_docs.
Confirmed the generated HTML displays the descriptions and cross-references accurately.

Partially fixes: #25904

Jonas Perolini 2bca09a191 Merge pull request #23190 from JonasPerolini:pr-output-marker-score
Include pixel-based confidence in ArUco marker detection #23190

The aim of this pull request is to compute a **pixel-based confidence** of the marker detection. The confidence [0;1] is defined as the percentage of correctly detected pixels, with 1 describing a pixel perfect detection. Currently it is possible to get the normalized Hamming distance between the detected marker and the dictionary ground truth [Dictionary::getDistanceToId()](https://github.com/opencv/opencv/blob/4.x/modules/objdetect/src/aruco/aruco_dictionary.cpp#L114) However, this distance is based on the extracted bits and we lose information in the [majority count step](https://github.com/opencv/opencv/blob/4.x/modules/objdetect/src/aruco/aruco_detector.cpp#L487). For example, even if each cell has 49% incorrect pixels, we still obtain a perfect Hamming distance.

**Implementation tests**: Generate 36 synthetic images containing 4 markers each (with different ids) so a total of 144 markers. Invert a given percentage of pixels in each cell of the marker to simulate uncertain detection. Assuming a perfect detection, define the ground truth uncertainty as the percentage of inverted pixels. The test is passed if `abs(computedConfidece - groundTruthConfidence) < 0.05` where `0.05` accounts for minor detection inaccuracies.

- Performed for both regular and inverted markers
- Included perspective-distorted markers
- Markers in all 4 possible rotations [0, 90, 180, 270]
- Different set of detection params:
    - `perspectiveRemovePixelPerCell`
    - `perspectiveRemoveIgnoredMarginPerCell`
    - `markerBorderBits`

![TestCases](https://github.com/user-attachments/assets/1113abd3-ff7a-45c8-8b4b-a9d2182eda82)


The code properly builds locally and `opencv_test_objdetect` and `opencv_test_core` passed. Please let me know if there are any further modifications needed. 

Thanks!


I've also pushed minor unrelated improvement (let me know if you want a separate PR) in the [bit extraction method](https://github.com/opencv/opencv/blob/4.x/modules/objdetect/src/aruco/aruco_detector.cpp#L435). `CV_Assert(perspectiveRemoveIgnoredMarginPerCell <=1)` should be `< 0.5`. Since there are margins on both sides of the cell, the margins must be smaller than half of the cell. When setting `perspectiveRemoveIgnoredMarginPerCell >= 0.5`, `opencv_test_objdetect` fails. Note: 0.499 is ok because `int()` will floor the result, thus `cellMarginPixels = int(cellMarginRate * cellSize)` will be smaller than `cellSize / 2`

Abhishek Shinde ea9b183d9b Merge pull request #28259 from falloficarus22:fix/bilateral-filter-oob
Fix the out-of-bounds read in cv::bilateralFilter for 32f images #28259

### Root Cause Analysis

The issue was caused by a discrepancy between the image range used to allocate the color weight look-up table (LUT) and the actual range of pixel values encountered during filtering, especially near the image borders.

- Range Computation: `cv::bilateralFilter` computes the min/max values of the source image and allocates a `LUT (expLUT)` of size `kExpNumBins + 2` based on this range.
- Border Padding: If `cv::BORDER_CONSTANT` is used (defaulting to 0), and 0 is outside the image's original range (e.g., an image with values between 100 and 200), the padded image will contain values (0) that create differences larger than those accounted for in the `LUT`.
- Out-of-Bounds Access: When calculating the color weight, the code computes an index `idx` from the absolute difference. If this difference exceeds the expected range, `idx` can reach or exceed `kExpNumBins + 1`. Since the code performs linear interpolation using `expLUT[idx]` and `expLUT[idx + 1]`, an `idx` of `kExpNumBins + 1` causes an access to `expLUT[kExpNumBins + 2]`, which is out of bounds.

### Fix

I implemented a robust clamping mechanism in both the SIMD (AVX/SSE) and scalar paths of the bilateral filter invoker:

- Signature Update: Updated `bilateralFilterInvoker_32f` to accept `kExpNumBins` (the maximum valid `LUT` index).
- Clamping: Clamped the computed color difference (alpha) to `kExpNumBins` before calculating the `LUT` index. This ensures that any difference exceeding the planned range is safely treated as the maximum difference in the `LUT` (which usually corresponds to a weight of 0), avoiding any out-of-bounds memory access.

### Modified Files

Modified Files:
`modules/imgproc/src/bilateral_filter.simd.hpp`: Updated the invoker class and SIMD/scalar loops to clamp the LUT index.
`modules/imgproc/src/bilateral_filter.dispatch.cpp`: Updated the dispatch call site to pass the correct LUT size.

Closes #28254

js: restore deep copy behavior for Mat.clone() #28216

### Problem
In OpenCV.js, `cv.Mat.clone()` may resolve to Embind `ClassHandle.clone()` (handle/shallow clone) instead of OpenCV deep copy.

### Changes
- modules/js/src/helpers.js: override `cv.Mat.prototype.clone` -> `mat_clone` after runtime init
- modules/js/test/test_mat.js: update/extend tests to validate deep copy semantics of `clone()`

Fixes  #27572
Related: PR #26643 (js_clone_fix), PR #27985 (documentation update)

### Verification
- Built OpenCV.js with Emscripten 2.0.10
- QUnit: bin/tests.html
- CoreMat: test_mat_creation (0 failures)

core: fix solveCubic numerical instability via coefficient normalization (fixes #27748) #28117

 Summary
This PR fixes numerical instability in `cv::solveCubic` when the leading coefficient `a` is non-zero but extremely small relative to other coefficients (Issue #27748). 

It introduces a **normalization step** that scales all coefficients by their maximum magnitude before solving. This ensures robust detection of when the equation should degenerate to a quadratic solver, without breaking valid cubic equations that happen to have small coefficients (e.g., scaled by 1e-9).

The Problem (Issue #27748)
The previous implementation checked `if (a == 0)` to decide whether to use the cubic or quadratic formula. 
- When `a` is extremely small (e.g., 1e-17) but not exactly zero, and other coefficients are normal (e.g., 5.0), the standard cubic formula suffers from catastrophic cancellation and overflow, producing incorrect roots (e.g., 1e14).

 The Fix
1. Normalization: The solver now finds `max_coeff = max(|a|, |b|, |c|, |d|)` and scales all coefficients by `1.0 / max_coeff`.
2. Relative Threshold: It then checks `if (abs(a) < epsilon)` on the *normalized* coefficients. 

 Why this is better than previous attempts
In a previous attempt (PR #28057), a simple absolute check `abs(a) < epsilon` was proposed. That approach was rejected because it failed for scaled equations.

satyam yadav 2b42788803 Merge pull request #28217 from satyam102006:feature/dis-coarsest-scale
[video] Add setCoarsestScale to DISOpticalFlow (Fixes #25068) #28217

### Description
This PR addresses issue #25068 regarding the number of scales in `DISOpticalFlow`.

Currently, `DISOpticalFlow` automatically computes the `coarsest_scale` based on the image size. While generally effective, this behavior can cause errors in specific use cases (e.g., mechanics/speckle pattern analysis) where high pyramid levels degrade quality.

This change introduces a manual override:
- Added `setCoarsestScale(int val)` and `getCoarsestScale()` to the public API.
- Updated `DISOpticalFlowImpl::calc` and `ocl_calc` to use the user-defined scale if set.
- Preserved the existing "automatic" behavior as the default (when set to -1).

### Changes
- **`modules/video/include/opencv2/video/tracking.hpp`**: Added virtual method declarations.
- **`modules/video/src/dis_flow.cpp`**: Implemented `set/getCoarsestScale` in `DISOpticalFlowImpl` and updated calculation logic.
- **`modules/video/test/test_OF_accuracy.cpp`**: Added `DenseOpticalFlow_DIS.ManualCoarsestScale` regression test.


Fixes #25068

HARSH SUMAN e3e87055bd Merge pull request #28195 from harsh-suman5:fix-coverage-regex
Fix regex escape warning in _coverage.py by using raw string #2819

while i am running '_coverage.py' I noticed there is a syntax warning:"\." It is an invalid escape sequence
The regex was written as a normal string with '\.' which is not valid escape in string literals and give problems and error in a new python versions. 
To fix this switch to raw string(r'cv2?\.\w+') which can passes the backslashes directly to the regex engine. This removes the warning and keeps the code  and pattern working properly.

This is a small fix but important for future compatibilities.

AdwaithBatchu 87f4a9782c Merge pull request #28203 from AdwaithBatchu:fix-macos-lapack-warnings
core: suppress LAPACK deprecation warnings on macOS #28203

### Description
On macOS (Apple Silicon) with newer Xcode/Clang, the CLAPACK interface is deprecated.
Compiling `hal_internal.cpp` triggers multiple warnings like:
`warning: 'sgesv_' is deprecated: first deprecated in macOS 13.3 - The CLAPACK interface is deprecated. [-Wdeprecated-declarations]`

Since migrating to the new Accelerate interface (Apple's recommended fix) requires significant changes to the HAL implementation and breaks the build if headers are mismatched, this PR takes the pragmatic approach. It suppresses the `-Wdeprecated-declarations` warning for this specific file using Clang pragmas to clean up the build output.

### Verification
- [x] Verified build is silent on macOS (M3).
- [x] Verified pragmas are correctly scoped within `HAVE_LAPACK` to prevent scope mismatch on non-LAPACK builds.

Emscripten 3.1.71+ introduced ClassHandle.clone() which performs a shallow copy.
This shadowed the original OpenCV clone() method which was intended for deep copying.

This patch:
1. Hooks into onRuntimeInitialized in helpers.js
2. Overrides cv.Mat.prototype.clone to point to mat_clone (deep copy)
3. Updates JS tests to use clone() to verify the fix

Alexander Smorkalov c03734475f Merge pull request #28159 from asmorkalov:as/java_cleaners
Introduce option to generate Java code with finalize() or Cleaners interface #28159
 
Closes https://github.com/opencv/opencv/issues/22260
Replaces https://github.com/opencv/opencv/pull/23467

The PR introduce configuration option to generate Java code with Cleaner interface for Java 9+ and old-fashion finalize() method for old Java and Android. Mat class and derivatives are manually written. The PR introduce 2 base classes for it depending on the generator configuration.

Pros:
1. No need to implement complex and error prone cleaner on library side.
2. No new CMake templates, easier to modify code in IDE.

Cons:
1. More generator branches and different code for modern desktop and Android.

TODO: 
- [x] Add Java version check to cmake
- [x] Use Cleaners for ANDROID API 33+

Alex 7ca9d9ce03 Merge pull request #27878 from 0lekW:ffmpeg-negative-dts-seeking-fix
Fix frame seeking with negative DTS values in FFMPEG backend #27878

**Merge with extra**: https://github.com/opencv/opencv_extra/pull/1289

Fixes https://github.com/opencv/opencv/issues/27819
Fixes https://github.com/opencv/opencv/issues/23472
Accompanied by PR on https://github.com/opencv/opencv_extra/pull/1289

The FFmpeg backend fails to correctly seek in H.264 videos that contain negative DTS values in their initial frames. This is a valid encoding practice used by modern video encoders (such as DaVinci Resolve's current export) where B-frame reordering causes the first few frames to have negative DTS values.

When picture_pts is unavailable (AV_NOPTS_VALUE), the code falls back to using pkt_dts:
`picture_pts = packet_raw.pts != AV_NOPTS_VALUE_ ? packet_raw.pts : packet_raw.dts;`

If this DTS value is negative (which is legal per H.264 spec), it propagates through the frame number calculation:
`frame_number = dts_to_frame_number(picture_pts) - first_frame_number;`

This results in negative frame numbers, messing up seeking operations.

Solution implemented in this branch is a timestamp normalization similar to FFmpegs -avoid_negative_ts_make_zero flag:
- Calculate a global offset once on the first decoded frame by getting the minimum timestamp in either:
    - Container start_time
    - Stream start_time
    - First observed timestamp (PTS, then DTS).
- Apply the offset consistently to all timestamps, shifting negative values to begin at 0 while keeping relative timing.
- Simplify timestamp converters to remove `start_time` subtractions since timestamps are pre-normalized.

This also includes a new test `videoio_ffmpeg.seek_with_negative_dts`
This test verifies that seeking behavior performs as expected on a file which has negative DTS values in the first frames. 
A PR on opencv_extra accompanies this one with that testing file: https://github.com/opencv/opencv_extra/pull/1279

satyam yadav 748d654535 Merge pull request #28173 from satyam102006:fix/issue-28165-videoio-ios-crash
videoio(ios): fix NSInvalidArgumentException in VideoWriter release #28173

Summary
Fixes a crash on iOS when calling `VideoWriter::release()` in OpenCV 4.12.0.

Issue
Fixes #28165

Detailed Description
This PR resolves a regression where an `NSInvalidArgumentException` was thrown with the message ` -[NSAutoreleasePool retain]: Cannot retain an autorelease pool`.

The crash was caused by the manual usage of `NSAutoreleasePool` in the `~CvVideoWriter_AVFoundation` destructor. The local pool variable was being captured by the completion handler block passed to `[mMovieWriter finishWritingWithCompletionHandler:]`. Since `NSAutoreleasePool` instances cannot be retained, capturing them in a block causes a crash.

Changes:
- Replaced manual `NSAutoreleasePool` allocation and draining with modern `@autoreleasepool` blocks in `CvVideoWriter_AVFoundation`.
- applied this modernization to the Constructor, Destructor, and `write` methods.
- Specifically in the destructor, an inner `@autoreleasepool` is now used inside the completion block, ensuring no pool object needs to be captured from the outer scope.

Ghazi-raad f704001eb7 Merge pull request #28120 from Ghazi-raad:test/line-connectivity-26413
Test: Add regression test for LINE_4 vs LINE_8 connectivity #28120 

Add test to verify correct behavior of LINE_4 (4-connected) and LINE_8 (8-connected) line drawing. This test ensures:

- LINE_4 produces staircase pattern (more pixels) for diagonal lines
- LINE_8 produces diagonal steps (fewer pixels)
- LINE_4 pixels have only horizontal/vertical neighbors (no diagonal-only)

Regression test for issue #26413 where LINE_4 and LINE_8 behaviors were swapped.

shubham khatri 498853d996 Merge pull request #28143 from Shubh3155:fix-js-ptr-factory-namespace
Fix JS bindings for namespaced Ptr factory return types #28143

This PR fixes an issue in the JS bindings generator for factory functions returning cv::Ptr<T> where T belongs to a namespaced class (for example cv::ximgproc::EdgeDrawing).
The generator previously produced unqualified C++ template arguments such as:
.constructor(select_overload<Ptr<EdgeDrawing>()>(&cv::ximgproc::createEdgeDrawing))

This results in invalid C++ because EdgeDrawing is not found in the global namespace.

Fixes https://github.com/opencv/opencv/issues/28130

In modules/js/generator/embindgen.py, inside both:

gen_function_binding_with_wrapper

gen_function_binding

a check is added:

When factory == True,

And the return type begins with Ptr<...>,

And the inner type is missing a namespace (::),
Ptr<T>  →  Ptr<class_info.cname>

This ensures the fully-qualified class name (e.g. cv::ximgproc::EdgeDrawing) is used in the generated bindings.

.constructor(select_overload<Ptr<cv::ximgproc::EdgeDrawing>()>(&cv::ximgproc::createEdgeDrawing))

Configured OpenCV with:
cmake .. -DBUILD_opencv_js=ON

Ran:
make -j gen_opencv_js_source

JS generator completed successfully without errors.

This change does not modify generated files directly — it modifies the generator logic so the correct namespace is applied automatically.

Ghazi-raad 5a0679b862 Fix null pointer dereference in G-API stateful kernels
Fixes #28095

Problem:
- Stateful kernels dereference null state pointer on line 446 in gcpukernel.hpp
- jinboson confirmed state_ptr is null on x86 Ubuntu (7 hours ago)
- Causes crash with std::shared_ptr assertion on LoongArch64 and strict platforms

Solution (addressing Copilot review feedback from PR #28096):
1. Added null pointer check using CV_Error instead of CV_Assert:
   - CV_Assert with && 'message' doesn't display the message correctly
   - CV_Error properly reports cv::Error::StsNullPtr with clear message

2. Fixed test kernels to properly initialize state using std::make_shared:
   - GOCVStInvalidResize: Initialize state in setup()
   - GOCVCountStateSetups: Initialize state before incrementing counter
   - Used std::make_shared<int>() for modern C++ best practice

Impact:
- Prevents crashes on platforms with strict null pointer checking
- Provides actionable error message for developers
- Fixes StatefulKernel.StateInitOnceInRegularMode and InvalidReallocatingKernel tests

Fixes #26870.

In `modules/stitching/src/cuda/build_warp_maps.cu`, the original implementation copied parameters into global GPU constant symbols:

```cpp
cudaSafeCall(cudaMemcpyToSymbol(build_warp_maps::ck_rinv, k_rinv, 9 * sizeof(float)));
cudaSafeCall(cudaMemcpyToSymbol(build_warp_maps::cr_kinv, r_kinv, 9 * sizeof(float)));
cudaSafeCall(cudaMemcpyToSymbol(build_warp_maps::cscale, &scale, sizeof(float)));
```

As discussed in the issue, this can cause race conditions when multiple warps are built concurrently. This patch removes the use of these global constant symbols and instead passes the required data as kernel parameters (a total of 11 floats encapsulated in `WarpParams`).

One potential concern is increased register pressure due to additional kernel arguments. However, based on experiments using the test case from issue #26870, there is no significant performance regression; in fact, a small speed‑up was observed.

Testing was performed on an NVIDIA GeForce RTX 4090 (single GPU).

Note: ./bin/opencv_perf_stitching did not run successfully on my system even with an unmodified git checkout, so performance was evaluated using the test case from issue #26870 instead.

satyam yadav fbd550438f Merge pull request #28073 from satyam102006:issue-OpenCV-to-MSMF-
catch _com_error exceptions to suppress debugger flooding #28073

Resolves: #27643

This PR fixes an issue where the Microsoft Media Foundation (MSMF) backend triggers repeated C++ exceptions (_com_error) during video capture. While these exceptions are often non-fatal "first-chance" exceptions, they cause the Visual Studio debugger to break execution repeatedly, making debugging difficulty and flooding the output window.

Changes
cap_msmf.cpp: Added try-catch blocks around critical COM interaction paths.

Updated SourceReaderCB::OnReadSample (Async callback) to catch _com_error.

Updated CvCapture_MSMF::grabFrame (Synchronous grab) to catch _com_error.

Added CV_LOG_WARNING to log the error message from the caught exception, ensuring that actual errors are still visible in the logs without crashing the application or halting the debugger.

Impact
Users debugging OpenCV applications on Windows with Visual Studio will no longer be interrupted by internal MSMF exceptions when using the default backend.

The application flow remains uninterrupted even if MSMF encounters transient internal errors.

fix: set default pixel format for Aravis cameras when unsupported format #28086

Fixes #26523

This PR fixes an issue where Aravis VideoCapture returns empty frames when the camera's pixel format is not explicitly set via CAP_PROP_FOURCC.

Problem:

The Aravis backend's retrieveFrame() function only processes four specific pixel formats:
- ARV_PIXEL_FORMAT_MONO_8
- ARV_PIXEL_FORMAT_BAYER_GR_8
- ARV_PIXEL_FORMAT_MONO_12
- ARV_PIXEL_FORMAT_MONO_16

If the camera has a different pixel format configured (or the camera's default format is unsupported), retrieveFrame() returns false on line 333 and all frames appear empty. This happens even though:
- The camera opens successfully (isOpened() returns true)
- The camera is capturing data
- The user has set up autotrigger and auto-exposure correctly

Root Cause:

In open() at line 271, the code retrieves the camera's current pixel format with arv_camera_get_pixel_format(). But if this format doesn't match one of the four supported formats, there's no fallback, causing all subsequent frames to fail retrieval.

Solution:

Added a check after retrieving the camera's pixel format. If the format is not one of the four supported formats, the code now:
1. Sets pixelFormat to a sensible default (MONO_8)
2. Applies this format to the camera via arv_camera_set_pixel_format()

This ensures:
- Cameras work out-of-the-box without requiring explicit CAP_PROP_FOURCC setup
- Users can still override the format with CAP_PROP_FOURCC if needed
- Behavior matches user expectations from other camera backends (V4L2, MSMF, etc.)

The default of MONO_8 was chosen because it's the most universally supported format across USB3 Vision and GigE Vision cameras.

Changes:

modules/videoio/src/cap_aravis.cpp: Added pixel format validation and default setting (10 lines)

Testing:

With this fix:
- Cameras with unsupported default formats will automatically switch to MONO_8
- The sample code from the issue works without uncommenting the CAP_PROP_FOURCC line
- Users can still explicitly set their preferred format via CAP_PROP_FOURCC

Fix tempfile race condition on Windows (issue #19648) #28087

Fix tempfile race condition on Windows

Addresses issue #19648

Problem
The cv::tempfile() function on Windows used GetTempFileNameA() followed by an immediate DeleteFileA() call. This created a race condition where multiple OpenCV processes running simultaneously could receive the same temporary filename, leading to name collisions.

Root Cause
The previous implementation:

Called GetTempFileNameA() to generate a temp filename
Immediately deleted the file to free the name
Returned just the filename string
Between steps 2 and 3, another process could call GetTempFileNameA() and receive the same filename, causing a collision.

Solution
Replaced GetTempFileNameA() with GUID-based filename generation using CoCreateGuid(), following the same approach already used in GetTempFileNameWinRT() and Microsoft's recommendations for scenarios requiring many temp files.

Changes
modules/core/src/system.cpp:

Removed GetTempFileNameA() and DeleteFileA() calls
Added CoCreateGuid() to generate unique GUID-based filenames
Format: "ocv{GUID}" where GUID ensures uniqueness across processes
Benefits

Eliminates race condition in multi-process scenarios
No file I/O overhead from creating and deleting placeholder files
Consistent with WinRT implementation approach
Follows Microsoft best practices
Testing
Standard OpenCV test suite. The change only affects Windows temp file naming and maintains the same String return type and usage pattern.

Fixed multiband blender memory leak 27333 #28085

Fixes #27333

This PR fixes a memory leak in MultiBandBlender where memory from pyramid vectors was not being released when prepare() was called multiple times or when the blender object was reused.

Problem:

MultiBandBlender retains hundreds of MB to several GB of memory even after the blender pointer is released. The issue occurs because:

1. The resize() function on std::vector does not release memory when the new size is less than or equal to the current size
2. It only adjusts the size marker while retaining the capacity and existing data
3. When prepare() is called, the pyramid vectors are resized but old data remains allocated

Example from the bug report: Blending 14 images (1920x1080) retained ~200MB after blender.release(). With larger images, several GB could be retained.

Root Cause:

GPU path (lines 254-256): Correctly calls clear() before operations
Non-GPU path (lines 285-298): Missing clear() calls, causing resize() to retain old data

Solution:

Added .clear() calls before .resize() in the non-GPU path to match the GPU path behavior. This ensures:
- Memory from previous blend operations is released in prepare()
- Reusing a blender object doesn't accumulate memory
- Behavior is consistent between GPU and non-GPU code paths

Changes:

modules/stitching/src/blenders.cpp: Added 2 clear() calls (dst_pyr_laplace_.clear() and dst_band_weights_.clear()) before resize() in the non-GPU path

Ghazi-raad a27a13921b Fix LINE_4/LINE_8 swap in drawContours (issue #26413)
Changed condition to correctly route LINE_8 to Line() instead of Line2().

The condition 'line_type == 1 || line_type == 4' was causing LINE_8 (value 8)
to be processed by Line2() which implements 4-connectivity, and LINE_4 (value 4)
to be processed by Line() which was implementing 8-connectivity behavior. This
resulted in swapped line connectivity.

Changed to 'line_type == 1 || line_type == 8' so LINE_8 goes to Line() with
8-connectivity and LINE_4 goes to Line2() with 4-connectivity, matching the
documented behavior where LINE_4 should produce 4-connected lines and LINE_8
should produce 8-connected lines.

Fix memory leak in pyopencv_to for path-like objects #28047
   
This PR fixes a memory leak in pyopencv_to when handling path-like objects (e.g., pathlib.Path).
Problem:
PyOS_FSPath() returns a new strong reference, but the code was not calling Py_XDECREF to decrement it, causing a memory leak on every call with path-like arguments.
Solution:

Store the returned reference from PyOS_FSPath() in a separate variable path_obj
Call Py_XDECREF(path_obj) on all function exit paths (both success and error paths)
This ensures proper reference counting without changing the function's behavior

Testing:
The leak can be reproduced using the steps in issue #28046 with Python built with --with-address-sanitizer. This fix ensures the reference is properly released.
Fixes #28046

Dmytro Dadyka 6231b080ff Merge pull request #27952 from DDmytro:ecc/template-mask-rework
Add optional template mask for findTransformECC #27952

Supersedes #22997

**Summary**
Add optional template mask support to findTransformECC so that only pixels valid in both the template and the image are used in ECC. Backward compatibility is preserved (existing signatures unchanged; one new overload adds templateMask).

**Motivation**

- Real-world frames often contain moving foreground artifacts (e.g., a football over a static field). Masking the object in one frame only is insufficient because its position changes independently of the background. Since we don’t know the warp a priori, we can’t back-project a single mask across frames. The correct approach is to supply both masks and take their intersection.
- Templates may include uninformative/low-texture or noisy regions, or partial overlaps with other objects. Excluding such regions from the alignment improves robustness and convergence.

This PR completes and replaces https://github.com/opencv/opencv/pull/22997

Adrian Kretz c0364e4e31 Merge pull request #27993 from akretz:undistortPoints_convergence
Undistort points convergence #27993

I have looked into the `undistortPoints()` problem of issue #27916 and have found a solution. The problem is, as @Linhuihang has correctly pointed out, that the fixed-point iterations do not converge. Here are the functions which are optimized for the undistortion problem:

$$
\begin{aligned}
  r^2  &= x'^2 + y'^2 \\
  f_1(x') &= \frac{1 + k_4 r^2 + k_5 r^4 + k_6 r^6}{1 + k_1 r^2 + k_2 r^4 + k_3 r^6} (x'' - 2p_1 x' y' - p_2(r^2 + 2 x'^2) - s_1 r^2 + s_2 r^4) = x' \\
  f_2(y') &=  \frac{1 + k_4 r^2 + k_5 r^4 + k_6 r^6}{1 + k_1 r^2 + k_2 r^4 + k_3 r^6} (y'' - p_1 (r^2 + 2 y'^2) - 2 p_2 x' y' - s_3 r^2 - s_4 r^4) = y'
\end{aligned}
$$

where $x', y'$ are the undistorted points we want to compute and and $x'', y''$ are the given distorted points. This problem is solved using fixed-point iterations like

$$
  x'_{k+1} = f_1(x'_k),\quad
  y'_{k+1} = f_2(y'_k)
$$

I guess the issue here is that the distortion function does not necessarily satisfy the [Banach fixed-point theorem](https://en.wikipedia.org/wiki/Banach_fixed-point_theorem), i.e. the slope of the function can be too large. This can be seen in @Linhuihang's comment https://github.com/opencv/opencv/issues/27916#issuecomment-3417883642 - the point series jumps around and doesn't converge.

A common solution is to instead do damped fixed-point iterations, so that the updates are "more smooth".

$$
  x'_{k+1} = (1 - \alpha) x'_k + \alpha f_1(x'_k),\quad
  y'_{k+1} = (1 - \alpha) y'_k + \alpha f_2(y'_k)
$$

I have implemented a simple logic which starts with $\alpha = 1$ (so just like it is now) and reduces $\alpha$ whenever the optimization error would increase. This seems reasonable to me: the initial logic is to do normal fixed-point iterations and to gradually become "more damped" when we notice that we don't converge. Perhaps there is a better way to ensure convergence, but this is the most straightforward modification to the current code that I have found.

This problem is not due to the $\tau_x, \tau_y$ parameters; it also occurs when they are zero. In fact, the fixed-point iterations are done when the tilt correction of $\tau_x, \tau_y$ has already been applied. I have added a test to reproduce the problem. This PR fixes #27916.

Added CMake define option to enforce IPP calls in IPP HAL when building with IPP integration #27925

Extra build option needed to simplify custom builds with IPP integration to ensure the IPP calls done even in cases when the results are not bitwise compliant to the reference OpenCV implementation. Option name is ```WITH_IPP_CALLS_ENFORCED```, and it is disabled by default.

Requested by some IPP customers and might be used in general as a way providing calls with better performance for the cases the aligned precision is not as important aspect.

Supposed to be used in HAL only, so added only in IPP HAL CMake, currently it affects only Warp Affine, Warp Perspective and Remap integrations since the results may vary depending on HW and algorithm implementations.

happy-capybara-man db207c88b0 Merge pull request #27985 from happy-capybara-man:docs/fix-mat-clone-js
docs(js): Fix Mat.clone() documentation to use mat_clone() for deep copy #27985

- Update code example to use ```mat_clone()``` instead of ```clone()```
- Add explanatory note about shallow copy issue due to Emscripten embind
Problem
- OpenCV.js documentation shows ```Mat.clone()``` usage, but this method performs shallow copy instead of deep copy due to Emscripten embind limitations, causing unexpected behavior where modifications to cloned matrices affect the original.

- Fixes documentation aspect of issue #27572

Force empty output type where it's defined in API #27972

The PR replaces:
- https://github.com/opencv/opencv/pull/27936
- https://github.com/opencv/opencv/pull/21059

Empty matrix has undefined type, so user code should not relay on the output type, if it's empty. The PR introduces some exceptions:
- copyTo documentation defines, that the method re-create output buffer and set it's type.
- convertTo has output type as parameter and output type is defined and expected.

Kumataro 3402fc1f6d imgcodecs: Suppress unknown metadata type warning 2025-11-09 09:59:55 +09:00
Samaresh Kumar Singh 603bc58d3b Fix #27968: Eliminate unnecessary type conversions in GrabCut initGMMs
Remove performance bottleneck caused by redundant type conversions in the
initGMMs() function's tight nested loops that iterate over all image pixels.

Changes:
- Changed storage vectors from Vec3f to Vec3b to store pixel data directly
  without intermediate conversion
- Modified kmeans preparation to convert Vec3b data to CV_32FC1 only when
  creating the Mat for clustering (using convertTo instead of per-pixel cast)
- Explicitly convert Vec3b to Vec3d only when calling addSample() method

Performance Impact:
Previously: Vec3b -> Vec3f (in loop) -> Vec3d (implicit in addSample)
Now: Vec3b (in loop) -> Vec3d (explicit, only in addSample call)

This eliminates one unnecessary type conversion per pixel in the tight loop,
reducing computational overhead especially for large images.

Samaresh Kumar Singh 7224bced8b Fix #27961: Support reproducible builds by making host system version optional
Add BUILD_INFO_SKIP_SYSTEM_VERSION option to exclude the host kernel version
from build outputs, enabling reproducible builds across systems with different
kernel versions.

Changes:
- Modified CMakeLists.txt to conditionally include CMAKE_HOST_SYSTEM_VERSION
  in the build platform status based on BUILD_INFO_SKIP_SYSTEM_VERSION flag
- Updated 3rdparty/tbb/CMakeLists.txt to set TBB_HOST_VERSION conditionally
- Modified 3rdparty/tbb/version_string.ver.cmakein to use the new variable

When BUILD_INFO_SKIP_SYSTEM_VERSION=ON is set, the host system version is
excluded from both the CMake status output and the TBB version strings,
producing identical binaries on equivalent build systems regardless of
kernel version differences.

Default behavior is unchanged (version included) for backward compatibility.

Ismail Abou Zeid 5fb4ce482c Merge pull request #27950 from ismailabouzeidx:feat/estimate-translation2d
[calib3d] Add estimateTranslation2D() #27950

Merge with opencv_extra PR: opencv/opencv_extra#1286

### **Description**

This PR adds a new API, `cv::estimateTranslation2D()`, to the **calib3d** module.  
It computes a **pure 2D translation** between two sets of corresponding points using robust methods (`RANSAC` and `LMedS`).  
The function mirrors the interface and behavior of `estimateAffine2D()` and `estimateAffinePartial2D()`, but constrains the transformation to translation only.

This model is particularly useful for cases where the motion between images is purely translational, such as:
- Aerial stitching and planar mosaics.  
- Image alignment in fixed-camera systems.  
- Lightweight pipelines where affine or homography models are unnecessarily complex.

The implementation introduces a new internal class `Translation2DEstimatorCallback` and integrates seamlessly into OpenCV’s existing robust estimation framework (`PointSetRegistrator`).

---

### **Key Features**
- Implements `cv::estimateTranslation2D()` in the `calib3d` module.
- Supports robust methods **RANSAC** and **LMedS**.  
- Adds accuracy and performance tests.  
- Provides full **C++ and Python bindings**.  
- Includes **Doxygen documentation** consistent with OpenCV’s standards.  
- Verified correctness across noise, outlier, and datatype variations.

---
### **Testing & Verification**

**Unit Tests** (`modules/calib3d/`)

- **Minimal sample:**  
  `test1Point` validates that a single correspondence recovers the correct translation under both **RANSAC** and **LMedS** across 500 randomized trials.  
- **Robustness to noise and outliers:**  
  `testNPoints` generates 100 correspondences, injects noise and outliers (≤40% for RANSAC, ≤50% for LMedS), and verifies that:  
  - Estimated **T** closely matches ground truth (`cvtest::norm(..., NORM_L2)`).  
  - Inlier mask consistency and correctness are maintained.  
- **Datatype conversion:**  
  `testConversion` checks mixed input datatypes (integer → float) to ensure correct conversion and consistent results.  
- **Input immutability:**  
  `dont_change_inputs` confirms that input arrays remain unchanged after function execution, mirroring affine behavior.

**Performance Tests** (`modules/calib3d/`)

- `EstimateTranslation2DPerf` benchmarks **RANSAC** and **LMedS** using:  
  - Point counts: 1000  
  - Confidence levels: 0.95  
  - Refinement iterations: 10, 0  
  
These tests confirm **numerical stability**, **performance scaling**, and **consistency** across datatypes and noise levels.

sirudoi 881774d872 Merge pull request #27930 from sirudoi:4.x
Add macOS support for Orbbec Gemini330 camera #27930

### Description of Changes
Adds macOS support for Orbbec Gemini330 in videoio by integrating OrbbecSDK v2. Completes the non-macOS work in [#27230](https://github.com/opencv/opencv/pull/27230).

#### Motivation

[#27230](https://github.com/opencv/opencv/pull/27230) skipped macOS. On macOS, UVC alone lacks required device controls; OrbbecSDK v2 provides them.

#### Key Change
 - macOS: fetch/link OrbbecSDK v2.5.5 (replaces v1.9.4).
 - videoio (macOS): switch OrbbecSDK API usage from v1 to v2.

Vladyslav Humennyy f692304c29 Remove mention of 'tangential lens distortion' from fisheye documentation.
In `fisheye::initUndistortRectifyMap` states, that the function 'compensate radial and tangential lens distortion'. But in fact, fisheye camera model in OpenCV does not uses tangential distortion. It uses only radial distortions, with 4 distortion k_1, k_2, k_3, k_4, which all are radial. In the code of the function all of those koeficients indeed are used as radial lens distortion coefficients. Possible reason of that issue is similar documentation of pinhole camera, that as first four coefficients uses 2 radial and 2 tangential lens distortion coefficients - k_1, k_2, p_1, p_2.

libtiff 4.5 introduced [per-TIFF error handlers](https://libtiff.gitlab.io/libtiff/functions/TIFFOpenOptions.html). This PR removes the global OpenCV error handlers and uses per-handle error handlers. This reduces any risks associated with modifying global state, e.g. if another library also tries to set the global error handlers and OpenCV clobbers them.

The current Gao P3P implementation does not cover all the degenerate cases, **see last line** in: https://github.com/opencv/opencv/blob/6d889ee74c94124f6492eb8f0d50946d9c31d8e9/modules/calib3d/src/p3p.cpp#L211-L221

<summary>OBSOLETE</summary>

To fix this, the USAC P3P from OpenCV 5 is used instead: https://github.com/opencv/opencv/blob/7e6da007cddcf83a527dfda95d57228fa5a535d3/modules/3d/src/usac/pnp_solver.cpp#L282

## Some results

### Old P3P vs new

In the following video, I have tried to highlight the viewpoints which cause issues:

https://github.com/user-attachments/assets/97bec6a6-4043-4509-b50e-a9856d6423bd

| | Old P3P    | New P3P |
| -------- | ------- | ------- |
| Mean (ms)  | 0.045701 | 0.024816 |
| Median (ms) | 0.025146 | 0.023193 |
| Std (ms)    | 0.028953    | 0.006124 |

### New P3P vs AP3P

https://github.com/user-attachments/assets/eaeb21dc-3ffd-4b6c-9902-4352f824aa45

The AP3 method is superior both in term of accuracy and computation time:

| | New P3P    | AP3P |
| -------- | ------- | ------- |
| Mean (ms)  | 0.043750 | 0.023442 |
| Median (ms) | 0.023193 | 0.021484 |
| Std (ms)    | 0.039920 | 0.005265 |

### New P3P vs AP3P (range test)

https://github.com/user-attachments/assets/572e7b7a-2966-4bed-8e0c-b93d863987dc

The implemented P3P method does not work well when the tag is small, at long range.

| | New P3P    | AP3P |
| -------- | ------- | ------- |
| Mean (ms)  | 0.031351 | 0.025189 |
| Median (ms) | 0.022217 | 0.020996 |
| Std (ms)    | 0.024920 | 0.009633 |

---

- I have tried to simplify the P3P code, hope I did not break the implementation code
- calculations are performed using double type for simplicity.
- code such as the following are redundant and no more needed and should be replaced by `cv::Rodrigues`:

Atri Bhattacharya e7728bb27d Fixed linking for HighGUI against Qt 6.9 and newer
Use `link_libraries` instead of `add_defintions` to link against Qt 6.9
and newer to avoid un-expanded generator expressions from Qt cmake files
being appended to linker flags when building the HighGUI module.

The actual bug is likely in how Qt cmake files end up with these
un-expanded generator expressions in the first place — see discussion in
https://bugreports.qt.io/browse/QTBUG-134774 — but the recommended way
to link against the library is to use `link_libraries` anyway, so this
fix should do the trick.

Fixes issue #27223.

Optional Known Foreground Mask for Background Subtractors #27810

- [x] The PR is proposed to the proper branch

      Patch to opencv_extra has the same branch name.
- [x] The feature is well documented and sample code can be built with the project CMake

### Description
This adds an optional foreground input mask parameter to the MOG2 and KNN background subtractors, in line with issue https://github.com/opencv/opencv/issues/26476

4 tests are added under test_bgfg2.cpp:
2 for each subtractor type (1 with shadow detection and 1 without)
A demo shows the feature with only 3 parameters and with a 4th optional foreground mask for both core subtractor types.

Note: To patch contrib inheritance of the background subtraction class, empty apply method which throws a not implemented error is added to contrib subclasses. This is done to keep the overloaded apply function as pure virtual. Contrib PR to be made and linked shortly.

- [x] To the best of my knowledge, the proposed patch is not based on a code under GPL or another license that is incompatible with OpenCV
- [X] The PR is proposed to the proper branch

- This PR improves the performance of the LSTM function on ARM64 targets.
- Added a NEON intrinsics implementation of the fastGEMM1T function and enabled its use in fully connected and recurrent layers file. 
- As a result, ARM64 now benefits from vectorized matrix–vector multiplications, leading to measurable performance improvements in the LSTM layer.
- This change is limited to ARM64 and does not affect other architectures.

**Performance impact:**
- The optimization significantly improves the performance of lstm functions on ARM64 targets.

Fix string property bindings in JS generator #27726

Fixes #27712

This PR fixes the binding generation logic in embindgen.py to correctly handle enum and string properties:
Enum properties now use binding_utils::underlying_ptr(&Class::property).
Standard string properties are bound directly with &Class::property.
Other properties continue to use the default template.

Testing:
Verified generated bindings locally to ensure the expected output for enums and strings.

- [x] I agree to contribute to the project under Apache 2 License.
- [x] To the best of my knowledge, the proposed patch is not based on a code under GPL or another license that is incompatible with OpenCV
- [x] The PR is proposed to the proper branch

- This PR improves the performance of the Weighted Filter function from the ximgproc module on Windows on ARM64.
- The optimization is achieved by unrolling two performance-critical loops in the generateCentersPP function in modules/core/src/kmeans.cpp, which is internally used by the Weighted Filter function.
- The unrolling is enabled only for ARM64 builds using #if defined(_M_ARM64) guards to preserve compatibility and maintain performance on other architectures.

**Performance Improvements:** 
- Improves execution time for Weighted Filter performance tests on ARM64 without affecting other platforms.

- [x] The PR is proposed to the proper branch

- This PR improves the performance of the detect function on Windows ARM64 targets.
- Added the defined(_M_ARM64) macro in agast.cpp and agast_score.cpp files, aligning ARM64 behavior with how x64 selects internal functions for computation.
- As a result, ARM64 now executes the same internal functions as x64 where applicable, leading to measurable performance improvements in detect function.
- This changes is limited to Windows ARM64 and does not affect other architectures

**Performance impact:**
- Detect function shows improved runtime on ARM64 targets due to reuse of existing efficient computation paths.

Set limitation to IPP Bilateral Filter tiles number to avoid too small tiles #27720

### Pull Request Readiness Checklist

This PR fixes the following issue in Bilateral Filter tiling in IPP integration: image ROI can't be closer to the image border than the filter window radius. This issue shows itself during separation of the image to tiles for multithreaded processing. If the tile size small enough, the second tile is closer to the upper image border than the bilateral filter radius, which leads to the incorrect result. To fix this, we need a limitation to the tile size - done in this PR.

_Note: red build status looks like unrelated to the current change_

libpng upgrade to 1.6.45 and cICP metadata support for PNG imwrite #27741

### Pull Request Readiness Checklist

resolves #24185

libpng docs: https://www.w3.org/TR/png-3/#cICP-chunk
similar code from ffmpeg: https://github.com/FFmpeg/FFmpeg/blob/a700f0f72d1f073e5adcfbb16f4633850b0ef51c/libavcodec/pngenc.c#L452-L456

So issue #24185 can be solved by replacing `cv.imwrite` in user's code to `cv.imwriteWithMetadata`:
```python
cv.imwriteWithMetadata("frame.png", frame, [cv.IMAGE_METADATA_CICP], np.array([[9, 18, 0, 1]], np.uint8))

### Pull Request Readiness Checklist

Previous `fit_and_check_ellipse` implementation was very weak - it only checks that points center lies inside ellipse.
Current implementation `fit_and_check_ellipse` checks that points RMS (Root Mean Square) algebraic distance is quite small. It means that on average points are near boundary of ellipse. Because for points on ellipse algebraic distance is equal to `0` and for points that are close to boundary of ellipse is quite small

Previous `check_pt_in_ellipse` implementation was incorrect. For points on ellipse `cv::norm(to_pt)` should be equal to `el_dist`.

I tested current implementation with following Python script:
```

import matplotlib.pyplot as plt
from matplotlib.patches import Ellipse

def check_pt_in_ellipse(pt, el):
    center, axes, angle = ellipse
    to_pt = pt - center
    el_angle = angle * np.pi / 180
    to_pt_r_x = to_pt[0] * np.cos(-el_angle) - to_pt[1] * np.sin(-el_angle)
    to_pt_r_y = to_pt[0] * np.sin(-el_angle) + to_pt[1] * np.cos(-el_angle)
    pt_angle = np.arctan2(to_pt_r_y / axes[1], to_pt_r_x / axes[0])
    x_dist = 0.5 * axes[0] * np.cos(pt_angle)
    y_dist = 0.5 * axes[1] * np.sin(pt_angle)
    el_dist = np.sqrt(x_dist * x_dist + y_dist * y_dist)
    assert abs(np.linalg.norm(to_pt) - el_dist) < 1e-10

utibenkei 28d410cecf Merge pull request #27567 from utibenkei:fix-java-wrapper-missing-vec4i
Enable Java wrapper generation for Vec4i #27567 
 
Fixes an issue where Java wrapper generation skips methods using Vec4i.
Related PR in opencv_contrib: https://github.com/opencv/opencv_contrib/pull/3988

The root cause was the absence of Vec4i in gen_java.json, which led to important methods such as aruco.drawCharucoDiamond() and ximgproc.HoughPoint2Line() being omitted from the Java bindings.

This PR includes the following changes:

- Added Vec4i definition to gen_java.json
- Updated gen_java.py to handle jintArray-based types properly
- ~~Also adjusted jn_args and jni_var for Vec2d and Vec3d to ensure correct JNI behavior~~

The modified Java wrapper generator successfully builds and includes the expected methods using Vec4i.

Andrei Tamas 252403bbf2 Merge pull request #27600 from atamas19:ov_output_clamping
G-API: Implement cfgClampOutputs option to OpenVINO Params #27600

Added the option `cfgClampOutputs` to control where output clamping is performed for OpenVINO models. When enabled, output values are clamped in the PrePostProcessor stage instead of by the device or plugin. This provides a consistent and standardized clamping method across devices, helping to maintain accuracy regardless of device-specific clamping behavior.

hal/riscv-rvv: implement FAST keypoint detection #27391

An implementation of FAST keypoint detection with NMS/noNMS version.

A new perf test is written, and the perf test is evaluated in two platforms: K1/K230.
Accelaration is achieved when threshold is high, however, weird stat shows that the acceleration doesn't work when threshold is low (the number of keypoint candidates is high).

### Issue
CUDA 13 deprecated some fields, resulting in build failures with CUDA 13. This updates to use the replacement API.

I saw that this page encouraged us to contribute no matter how small the contribution is so I decided to "shoot my shot" as a beginner developer and fix a small grammatical error. Would be nice if I could be allowed to be recognized as a contributor with my contribution albeit pretty small, hopefully in the future, more meaningful contributions will be made! :)

Take into account overflow for connected components #27582

### Pull Request Readiness Checklist

Fix #27568 

The problem was caused by a label type overflow (`debug_example.npy` contains `92103` labels, that doesn't fit in the `CV_16U` (`unsigned short`) type). If pass `CV_32S` instead of `CV_16U` as `ltype` - everything will be calculated successfully

Added overflow detection to throw exception with a clear error message instead of strange segfault/assertion error

Sam Carlberg 84ca221184 Set Automatic-Module-Name manifest attribute
This is a useful property for modularized libraries and applications to be able to use OpenCV

A full module-info.java file for true compatibility with the Java module system would require compiling with Java 9+ and either use a multi-release JAR (which can be tricky to maintain) or compile the entire library with Java 9+ (which would break Android consumers on older SDK versions). In the interest of causing the least disruption, only an automatic module name is set so that modular Java 9+ consumers can use OpenCV but not break anybody else.

G-API: Implement cfgEnsureNamedTensors option to OpenVINO Params #27549

Added the option cfgEnsureNamedTensors to be applied on OpenVINO models with nameless tensors. If a tensor doesn't have a name, it sets a default one. The default name is created using OpenVINO's standard `make_default_tensor_name` . `make_default_tensor_name`  had to be rewritten because it is only available in OpenVINO's dev_api.

Add Raspberry Pi 4 and 5 V4L2 Stateless HEVC Hardware Acceleration with FFmpeg #27453

This PR enables V4L2 stateless HEVC hardware acceleration for Raspberry Pi 5 within OpenCV's videoio module. It leverages FFmpeg's drm acceleration ([FFmpeg API changes](https://github.com/FFmpeg/FFmpeg/blob/ee1f79b0fa4c82da9c19328b049b593c71611402/doc/APIchanges#L1529)), significantly improving HEVC decoding performance on RPi5 for robotics and embedded vision applications.

I have a working proof-of-concept with local benchmarks showing clear gains.

Checklist Status:

Ready: License, branch (4.x), FFmpeg reference, and (linked) related issue (#27452).
Seeking Guidance: Need help with formal C++ performance/accuracy tests, opencv_extra integration, and full documentation/examples.
As a Python developer, I welcome C++ best practice feedback and assistance with testing setup.

Sachin Shah 4c024c35fb Merge pull request #27523 from inventshah:fix-set-then-get-pos
FIX: CvCapture_FFMPEG::setProperty(CAP_PROP_POS_*) followed by getProperty #27523

Partially fixes #23088 and #23472. This PR fixes `get(CAP_PROP_POS_MSEC)` calls after a `set(CAP_PROP_POS_*)` without calling `read` first.

Since `seek` calls `grabFrame` which already sets `picture_pts`, manually setting `picture_pts` anywhere else in the call stack should not be necessary (except for the special case of seeking to frame 0).

Minimal example from #23088
```cpp
for(int i = 0; i < 3; i++) cap.read(img);
printf("at: %f frames, %f msec\n", cap.get(CAP_PROP_POS_FRAMES), cap.get(CAP_PROP_POS_MSEC));

cap.set(CAP_PROP_POS_FRAMES, 3);
printf("at: %f frames, %f msec\n", cap.get(CAP_PROP_POS_FRAMES), cap.get(CAP_PROP_POS_MSEC));
```

Current

```

at: 3.000000 frames, 80.000000 msec
at: 3.000000 frames, 80.000000 msec
```

It similarly helps with `CAP_PROP_POS_MSEC`:

Current
```txt
at: 3.000000 frames, 80.000000 msec
at: 2.000000 frames, 6.250000 msec
```

PR
```txt
at: 3.000000 frames, 80.000000 msec
at: 2.000000 frames, 40.000000 msec
```

Note the seek operation is still inconsistent between the `CAP_PROP_POS_*` options as mentioned by #23088, and VFR video seeking has issues discussed in #9053. For fixed-frame rate video, we could change 0.5 to 1 in `void CvCapture_FFMPEG::seek(double sec);` to align `CAP_PROP_POS_MSEC` with `CAP_PROP_POS_FRAMES`, but `CAP_POS_AVI_RATIO` and VFR video would still be broken.

Rita Melo 439b6af379 feat: G-API: Custom stream sources in Python (#27276)
Implemented:

- A C++ proxy class PythonCustomStreamSource that implements the
  IStreamSource interface. This class acts as a bridge between
  G-API’s internal streaming engine and user-defined Python
  objects. Internally, it stores a reference to a Python object
  (PyObject*) and is responsible for: calling the Python object’s
  pull() method to retrieve the next frame, calling the descr_of()
  method to obtain the frame format description, acquiring and
  releasing the Python GIL as needed, converting the returned
  numpy.ndarray into cv::Mat, and handling any exceptions or
  conversion errors with proper diagnostics.

- A Python-facing factory function, cv.gapi.wip.make_py_src(),
  which takes a Python object as an argument and wraps it into a
  cv::Ptr<IStreamSource>. Internally, this function constructs a
  PythonCustomStreamSource instance and passes the Python object to
  it. This design allows Python users to define any class that
  implements two methods: pull() and descr_of(). No subclassing or
  special decorators are required on the Python side. The user
  simply needs to implement the expected interface.
