##### Issue submission checklist
- [ ] I report the issue, it's not a question
<!--
2021-01-20 02:54:05 +08:00
OpenCV team works with forum.opencv.org, Stack Overflow and other communities
2022-01-15 10:49:38 +08:00
to discuss problems. Tickets with questions without a real issue statement will be
2020-02-28 15:01:24 +08:00
closed.
-->
- [ ] I checked the problem with documentation, FAQ, open issues,
2022-01-15 10:49:38 +08:00
forum.opencv.org, Stack Overflow, etc and have not found any solution
2020-02-28 15:01:24 +08:00
<!--

2022-01-15 10:49:38 +08:00
- [ ] I updated to the latest OpenCV version and the issue is still there
2020-02-28 15:01:24 +08:00
<!--
master branch for OpenCV 4.x and 3.4 branch for OpenCV 3.x releases.
2022-01-15 10:49:38 +08:00
OpenCV team supports only the latest release for each branch.
The ticket is closed if the problem is not reproduced with the modern version.
2020-02-28 15:01:24 +08:00
-->
- [ ] 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
2022-01-15 10:49:38 +08:00
* Attach the image as an archive to the ticket, if you report some reader issue.
2020-02-28 15:01:24 +08:00
Image hosting services compress images and it breaks the repro code.
2022-01-15 10:49:38 +08:00
* Provide ONNX file for some public model or ONNX file with random weights,
2020-02-28 15:01:24 +08:00
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/
