Awesome, powerful and simple to use library with BSD license. If you work in computer vision or any close fields it is exactly what could increase your efficiency an order of magnitude or even more. Thanks to developers... I love you
It is one of the best designed libraries I have seen for C++ (after Qt of course :)). The API is neat, it has C, Python, Java bindings. What else would you want?
Thanks for Opencvlibrary, it's excellent!
This app really help me a lot!
