Today, I tried to use OpenCV library on iPhone OS.
OpenCV is famous computer vision library used by many people working on image processing and computer vision. It is written in C language and platform independent (Windows, Linux, and Mac OS).
I included the two main library OpenCV (cv and cxcore) in my project and wrote small image processing codes (thresholding, edge detection, and blur) using OpenCV functions. The project was successfully built without errors.
I tried it on the simulator only. The performance on the real device should be checked. I hope OpenCV to work in real-time on iPhone/touch. ;-)
