If you are a serious computer vision researcher, you should consider to read this book. I started to use OpenCV since its beta version, and now I am still using the latest version. OpenCV helps me a lot in building real-time application that requires fast computation. Five stars for OpenCV authors, thanks for sharing a useful software and book for the rest of us
Complete material of what is OpenCV. The programming of computer vision. Theory, basis, implementation, and it's explanation. Including viewed from the physics science, it's describing it with a simple way but clear enough.
It was an ok introduction back when I read it, but new, matlab inspired, C++ API of OpenCV 2.0 weren't around back then, so the code samples are to a great extent outdated.
