Using OpenCV's Haar cascade face detection functionality, I was able to throw together a realtime head tracking program. I coupled this with a 3D "virtual window" demo, a homage to Johnny Lee's Wii-based head tracking demo. Performance is suprisingly good. On my 2.16 Ghz MacBook I am tracking at 25 frames per second - sufficient for realtime intereaction with no obtrusive reaction delays. Additionally, I've optimized the code so that only 50% of a single processor core is consumed (and that's on my realitively slow laptop).   Quicktime Video - Johnny Lee style targets Quicktime Video - 3D Objects     Go to Home Page Go to Projects Page
