Technical Support

There is no formal technical support for OpenCV, but there is a very active OpenCV Forum at Yahoo Groups where you are welcome to post your questions. A mirror of the group archive can be found at Gmane.

Bug Report Page

• Submit bugs: Report a bug or request new features or raise documentation issues on our bug tracking page.

  • You will first need to register at https://code.ros.org/gf/ (This is only for spam control, your name is not given out). Then:

  • Click on "new ticket" to file a new bug report or feature request, or submit a patch.
  • Click on "view tickets" or "search" to look for existing tickets - probably your problem is already known or even fixed in the latest SVN version.

• Bug Notes:

  • Do the work: Submit as much information as you can (what OS, what compiler, what OpenCV version).
  • To help rapidly fix the bug, it is preferable to also attach a short program plus data that reproduces the problem.
  • You can and should submit bugs for documentation. Again, be specific (C, C++, Python). What exactly was missing, confusing or wrong.
    • If you know how the documentation should be fixed, submit that too.
