The development of some buzamoto internal research projects has resulted in CVOCV: A CoreVideo-based OpenCV experimentation environment. CVOCV is an XCode-based project that provides programmers with an extremely simple way to access and experiment with OpenCV. CVOCV is clean, fast, and understandable.  If you ever wanted to learn OpenCV on OS X without much hassle, download it from the buzamoto wiki and have a look.
