-##### Issue submission checklist

- - [ ] I report the issue, it's not a question
-   <!--
-   OpenCV team works with answers.opencv.org, Stack Overflow and other communities
-   to discuss problems. Tickets with question without real issue statement will be
-   closed.
-   -->
- - [ ] I checked the problem with documentation, FAQ, open issues,
-       answers.opencv.org, Stack Overflow, etc and have not found solution
-   <!--
-   Places to check:
-   * OpenCV documentation: https://docs.opencv.org
-   * FAQ page: https://github.com/opencv/opencv/wiki/FAQ
-   * OpenCV forum: https://answers.opencv.org
-   * OpenCV issue tracker: https://github.com/opencv/opencv/issues?q=is%3Aissue
-   * Stack Overflow branch: https://stackoverflow.com/questions/tagged/opencv
-   -->
- - [ ] I updated to latest OpenCV version and the issue is still there
-   <!--
-   master branch for OpenCV 4.x and 3.4 branch for OpenCV 3.x releases.
-   OpenCV team supports only latest release for each branch.
-   The ticket is closed, if the problem is not reproduced with modern version.
-   -->
- - [ ] There is reproducer code and related data files: videos, images, onnx, etc
-   <!--
-   The best reproducer -- test case for OpenCV that we can add to the library.
-   Recommendations for media files and binary files:
-   * Try to reproduce the issue with images and videos in opencv_extra repository
-     to reduce attachment size
-   * Use PNG for images, if you report some CV related bug, but not image reader
-     issue
-   * Attach the image as archite to the ticket, if you report some reader issue.
-     Image hosting services compress images and it breaks the repro code.
-   * Provide ONNX file for some public model or ONNX file with with random weights,
-     if you report ONNX parsing or handling issue. Architecture details diagram
-     from netron tool can be very useful too. See https://lutzroeder.github.io/netron/

-FindCUDNN
----------
-
-Finds the cuDNN library.
-
-Requires:
-^^^^^^^^^
-
-find_cuda_helper_libs from FindCUDA.cmake
-i.e. CUDA module should be found using FindCUDA.cmake before attempting to find cuDNN
-
-Result Variables
-^^^^^^^^^^^^^^^^
-
-This will define the following variables:
-
-``CUDNN_FOUND``
-``CUDNN_INCLUDE_DIRS``    location of cudnn.h
-``CUDNN_LIBRARIES``       location of cudnn library
-
-Cache Variables
-^^^^^^^^^^^^^^^
-
-The following cache variables will be set if cuDNN was found. They may also be set on failure.
-
-``CUDNN_LIBRARY``
-``CUDNN_INCLUDE_DIR``
-``CUDNN_VERSION``
-
-``CUDNN_VERSION_MAJOR`` INTERNAL
-``CUDNN_VERSION_MINOR`` INTERNAL

+
+Goal
+----
+
+For the OpenCV developer team it's important to constantly improve the library. We are constantly
+thinking about methods that will ease your work process, while still maintain the libraries
+flexibility. The new C++ interface is a development of us that serves this goal. Nevertheless,
+backward compatibility remains important. We do not want to break your code written for earlier
+version of the OpenCV library. Therefore, we made sure that we add some functions that deal with
+this. In the following you'll learn:
+
+-   What changed with the version 2 of OpenCV in the way you use the library compared to its first
+    version
+-   How to add some Gaussian noise to an image
+-   What are lookup tables and why use them?
+
+General
+-------
+
+When making the switch you first need to learn some about the new data structure for images:
+@ref tutorial_mat_the_basic_image_container, this replaces the old *CvMat* and *IplImage* ones. Switching to the new
+functions is easier. You just need to remember a couple of new things.
+
+OpenCV 2 received reorganization. No longer are all the functions crammed into a single library. We
+have many modules, each of them containing data structures and functions relevant to certain tasks.
+This way you do not need to ship a large library if you use just a subset of OpenCV. This means that
+you should also include only those headers you will use. For example:
+@code{.cpp}
+#include <opencv2/core.hpp>
+#include <opencv2/imgproc.hpp>
+#include <opencv2/highgui.hpp>
+@endcode
+All the OpenCV related stuff is put into the *cv* namespace to avoid name conflicts with other
+libraries data structures and functions. Therefore, either you need to prepend the *cv::* keyword
+before everything that comes from OpenCV or after the includes, you just add a directive to use
+this:
+@code{.cpp}
+using namespace cv;  // The new C++ interface API is inside this namespace. Import it.
+@endcode
+Because the functions are already in a namespace there is no need for them to contain the *cv*
+prefix in their name. As such all the new C++ compatible functions don't have this and they follow
+the camel case naming rule. This means the first letter is small (unless it's a name, like Canny)
+and the subsequent words start with a capital letter (like *copyMakeBorder*).
+
+Now, remember that you need to link to your application all the modules you use, and in case you are
+on Windows using the *DLL* system you will need to add, again, to the path all the binaries. For
+more in-depth information if you're on Windows read @ref tutorial_windows_visual_studio_opencv and for
+Linux an example usage is explained in @ref tutorial_linux_eclipse.
+
+Now for converting the *Mat* object you can use either the *IplImage* or the *CvMat* operators.
+While in the C interface you used to work with pointers here it's no longer the case. In the C++
+interface we have mostly *Mat* objects. These objects may be freely converted to both *IplImage* and
+*CvMat* with simple assignment. For example:
+@code{.cpp}
+Mat I;
+IplImage pI = I;
+CvMat    mI = I;
+@endcode
+Now if you want pointers the conversion gets just a little more complicated. The compilers can no
+longer automatically determinate what you want and as you need to explicitly specify your goal. This
+is to call the *IplImage* and *CvMat* operators and then get their pointers. For getting the pointer
+we use the & sign:
+@code{.cpp}
+Mat I;
+IplImage* pI     = &I.operator IplImage();
+CvMat* mI        =  &I.operator CvMat();
+@endcode
+One of the biggest complaints of the C interface is that it leaves all the memory management to you.
+You need to figure out when it is safe to release your unused objects and make sure you do so before
+the program finishes or you could have troublesome memory leaks. To work around this issue in OpenCV
+there is introduced a sort of smart pointer. This will automatically release the object when it's no
+longer in use. To use this declare the pointers as a specialization of the *Ptr* :
+@code{.cpp}
+Ptr<IplImage> piI = &I.operator IplImage();
+@endcode
+Converting from the C data structures to the *Mat* is done by passing these inside its constructor.
+For example:
+@code{.cpp}
+Mat K(piL), L;
+L = Mat(pI);
+@endcode
+
+A case study
+------------
+
+Now that you have the basics done [here's](https://github.com/opencv/opencv/tree/3.4/samples/cpp/tutorial_code/core/interoperability_with_OpenCV_1/interoperability_with_OpenCV_1.cpp)
+an example that mixes the usage of the C interface with the C++ one. You will also find it in the
+sample directory of the OpenCV source code library at the
+`samples/cpp/tutorial_code/core/interoperability_with_OpenCV_1/interoperability_with_OpenCV_1.cpp` .
+To further help on seeing the difference the programs supports two modes: one mixed C and C++ and
+one pure C++. If you define the *DEMO_MIXED_API_USE* you'll end up using the first. The program
+separates the color planes, does some modifications on them and in the end merge them back together.
+
+@snippet interoperability_with_OpenCV_1.cpp head
+@snippet interoperability_with_OpenCV_1.cpp start
+
+Here you can observe that with the new structure we have no pointer problems, although it is
+possible to use the old functions and in the end just transform the result to a *Mat* object.
+
+@snippet interoperability_with_OpenCV_1.cpp new
+
+Because, we want to mess around with the images luma component we first convert from the default BGR
+to the YUV color space and then split the result up into separate planes. Here the program splits:
+in the first example it processes each plane using one of the three major image scanning algorithms
+in OpenCV (C [] operator, iterator, individual element access). In a second variant we add to the
+image some Gaussian noise and then mix together the channels according to some formula.
+
+The scanning version looks like:
+
+@snippet interoperability_with_OpenCV_1.cpp scanning
+
+Here you can observe that we may go through all the pixels of an image in three fashions: an
+iterator, a C pointer and an individual element access style. You can read a more in-depth
+description of these in the @ref tutorial_how_to_scan_images tutorial. Converting from the old function
+names is easy. Just remove the cv prefix and use the new *Mat* data structure. Here's an example of
+this by using the weighted addition function:
+
+@snippet interoperability_with_OpenCV_1.cpp noisy
+
+As you may observe the *planes* variable is of type *Mat*. However, converting from *Mat* to
+*IplImage* is easy and made automatically with a simple assignment operator.
+
+@snippet interoperability_with_OpenCV_1.cpp end
+
+The new *imshow* highgui function accepts both the *Mat* and *IplImage* data structures. Compile and
+run the program and if the first image below is your input you may get either the first or second as
+output:
+
+![](images/outputInteropOpenCV1.jpg)
