Abstract
A method for tracking heads and faces is disclosed wherein a variety of different representation models can be used to define individual heads and facial features in a multi-channel capable tracking algorithm. The representation models generated by the channels during a sequence of frames are ultimately combined into a representation comprising a highly robust and accurate tracked output. In a preferred embodiment, the method conducts an initial overview procedure to establish the optimal tracking strategy to be used in light of the particular characteristics of the tracking application.
