Obsolete links

Main OpenCV repository has been converted to git and compactified. History begins with the famous "atomic bomb" commit which dates back to May 11, 2010 and all prior commits are stored in the separate "OpenCV Attic" repository: https://github.com/opencv/opencv_attic

Old issue tracker has been moved to read-only state and will be kept for some time.
