Tracking failure is an inevitable problem in any objecttracking algorithm. Online evaluation of a tracking algorithm todetect and correct failures is therefore an important task in anyobject tracking system. In this paper we propose an earlytracking failure detection procedure for the ContinuouslyAdaptive Mean-Shift(CAMShift) tracking algorithm. We alsopropose an algorithm to modify the tracker in order to correctthe detected failures. CAMShift is a light-weight trackingalgorithm first developed based on mean-shift to track humanface as a component in a perceptual user interface, but it easilyfails in tracking targets in more complex situations likesurveillance applications. With our proposed failure detectionand correction algorithm, CAMShift shows promising results inthe test video sequences
