Track and follow faces
Jun 14^th, 2009, 11:56am

I just started playing with Processing yesterday. After a few hours, I was able to have Processing talking with an Arduino, the arduino talking with some servos, and the computer tracking the faces.

OpenCV finds the faces in view of an iSight. I do some math and calculate the difference from the center of the image. I then take that difference, and instruct the servos to move the face to within 30 pixels of the center point (this takes care of it jittering around).

Along the way, I add some overlays and record each frame.

It is a bit slow right now and the servos are a little slow to move into place. I am only moving it one degree at a time. I plan on making it a little smarter, so that if a face is farther from the center it moves faster, etc.

IMHO, not too bad for a few hours of fooling around.

If anyone wants to see the source code, I'll be happy to post that too.
