Computer Vision

My brother has been hacking Kinects to see how accurately it can track people and recognize object. I thought I’d try using a normal (non IR, 3D) camera to see what results I could get. As such, I stumbled upon the openCV library – which is pretty incredible. I am using openCV, Xcode on Snow Leopard. My first trial was somewhat successful. A) The computer managed to identify people B) it was able to do so in realtime.

Unfortunately, it also mistook polls or anything that had high contrasting rectangular shapes as people – as you can see from the screen grab below.

I used the following online resources:
