Robust Tracking of People, Hands and Faces
Paper by James L. Crowley and co-authors
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.
