Webcam head tracking in immersive 3d environment

Check the project page at http://code.google.com/p/ehci/
This video shows my approach to combine OpenCV head tracking with a 3d OpenGL environment so that the user will see objects from their head's point of view. Since headtracking is 2d, no depth information is obtained. Besides that, it takes around 200ms for the face recognition algorithm, which gives a low refresh rate. I'm currently trying to improve that.

Try updating OpenCV from CVS, then use CV_HAAR_FIND_BIGGEST_OBJECT flag. Still 200ms or 20ms now?

Cheers, have fun!

Man, that was fast!

I'm really getting 20ms and the sensation is way better :)

Are you one of the OpenCV developers?

I've seen your "Low-cost Remote Eyetracking for 19" Display", it is really cool!

I'm only head tracking. When I get some time, I'll try to see your approach to eyetracking (it seems to be working fine for the video Accuracy test).

Are you in a Master or PhD program?

Thanks for your help,

Dan

I'm just a user. This valuable hint originates to Vadim Pisarevsky, who posted it in the OpenCV mailing list at Y*h** (I'm trying to avoid surreptitious advertising). Honour to whom honour is due: AFAIK Vadim did the latest optimisations in cvHaarDetectObjects.

noticed you liked visual effects videos and i thought you would also like mine.
