Robust Tracking of People, Hands and Faces

Paper by James L. Crowley and co-authors

Approach:

We imploy a modular tracker architecture that combines the advantages of several simple and rapidly performing tracking algorithms. Robust tracking is facilitated by frame-rate or near-frame-rate processing. A Kalman filter is used to integrate tracking results across detection modules and across time. Processing regions are smoothly localized by weighting with a Gaussian that is dimensioned according to the target sizes and uncertainties estimated by the Kalman filter. The result is an adaptive tracker that can robustly track several targets at video frame rates, and whose performance degrades gracefully with increasing system load.
