+
+Please:
+
+* Read the documentation to test with the latest developer build.
+* Check if other person has already created the same issue to avoid duplicates. You can comment on it if there already is an issue.
+* Try to be as detailed as possible in your report.

-##### 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 archive 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/

 CHANGE LOG for Independent JPEG Group's JPEG software


-Version 9d  12-Jan-2020
-----------------------
-
-Optimize the optimal Huffman code table generation to produce
-slightly smaller files.  Thank to John Korejwa for suggestion.
-Note: Requires rebuild of testimgp.jpg.
-
-Decoding Huffman: Use default tables if tables are not defined.
-Thank to Simone Azzalin for report (Motion JPEG),
-and to Martin Strunz for hint.
-
-Add sanity check in optimal Huffman code table generation.
-Thank to Adam Farley for suggestion.
-
-rdtarga.c: use read_byte(), with EOF check, instead of getc()
-in read_*_pixel().
-Thank to Chijin Zhou for cjpeg potential vulnerability report.
-
-jmemnobs.c: respect the max_memory_to_use setting in
-jpeg_mem_available() computation.  Thank to Sheng Shu and
-Dongdong She for djpeg potential vulnerability report.
-
-jdarith.c, jdhuff.c: avoid left shift of negative value
-compiler warning in decode_mcu_AC_refine().
-Thank to Indu Bhagat for suggestion.
-
-Add x64 (64-bit) platform support, avoid compiler warnings.
-Thank to Jonathan Potter, Feiyun Wang, and Sheng Shu for suggestion.
-
-Adjust libjpeg version specification for pkg-config file.
-Thank to Chen Chen for suggestion.
-
-Restore GIF read and write support from libjpeg version 6a.
-Thank to Wolfgang Werner (W.W.) Heinz for suggestion.
-
-Improve consistency in raw (downsampled) image data processing mode.
-Thank to Zhongyuan Zhou for hint.
-
-Avoid out of bounds array read (AC derived table pointers)
-in start pass in jdhuff.c.  Thank to Peng Li for report.
-
-Improve code sanity (jdhuff.c).
-Thank to Reza Mirzazade farkhani for reports.
-
-Add jpegtran -drop option; add options to the crop extension and wipe
-to fill the extra area with content from the source image region,
-instead of gray out.
