32 ##### Issue submission checklist
34 - [ ] I report the issue, it's not a question
36 OpenCV team works with forum.opencv.org, Stack Overflow and other communities
37 to discuss problems. Tickets with questions without a real issue statement will be
40 - [ ] I checked the problem with documentation, FAQ, open issues,
41 forum.opencv.org, Stack Overflow, etc and have not found any solution
44 * OpenCV documentation: https://docs.opencv.org
45 * FAQ page: https://github.com/opencv/opencv/wiki/FAQ
46 * OpenCV forum: https://forum.opencv.org
47 * OpenCV issue tracker: https://github.com/opencv/opencv/issues?q=is%3Aissue
48 * Stack Overflow branch: https://stackoverflow.com/questions/tagged/opencv
50 - [ ] I updated to the latest OpenCV version and the issue is still there
52 master branch for OpenCV 4.x and 3.4 branch for OpenCV 3.x releases.
53 OpenCV team supports only the latest release for each branch.
54 The ticket is closed if the problem is not reproduced with the modern version.
56 - [ ] There is reproducer code and related data files: videos, images, onnx, etc
58 The best reproducer -- test case for OpenCV that we can add to the library.
59 Recommendations for media files and binary files:
60 * Try to reproduce the issue with images and videos in opencv_extra repository
61 to reduce attachment size
62 * Use PNG for images, if you report some CV related bug, but not image reader
64 * Attach the image as an archive to the ticket, if you report some reader issue.
65 Image hosting services compress images and it breaks the repro code.
66 * Provide ONNX file for some public model or ONNX file with random weights,
67 if you report ONNX parsing or handling issue. Architecture details diagram
68 from netron tool can be very useful too. See https://lutzroeder.github.io/netron/
