Actuallly, I recalled that I did try to get into OpenCV few years back ago, when I knew no Python and when Python opencv module was probably still early. It was all C++ code and it was a little bit too hard for me. I read a couple of books about opencv at the library, I did not understand a single thing. That was back then.
