Real-Time Face Tracking Based on Boosted Face Filter

　

Multiple face tracking is performed based on the output of a boosted face filter. The boosted face filter is built to initialize the tracking and to provide a likelihood estimate to guide and update the tracking model. Gradient search combined with template tracking are used to improve the efficiency. No assumption about the stationary of the background is made; nor is skin color used. The resulting system can deal with varying number of faces, face appearance changes, short time mutual occlusion, and moving background. It runs at about 25 fps for 320x240 images on P4 1.4GHz PC.
