An appearance model (modified Exemplar View histogram, 380) is created (930) based on the region (150) in the first image frame and a background region (305) in a second image frame (101), an dthe method determines (940,950) at least one of a location and size of a predicted region (430) for tracking the object in the second image frame using the appearance model. The method corrects (960-980) at least one of the determined location and size (420) of the predicted region in the second image frame in accordance with at least one of the location and size of the region in the first image frame corresponding to the exemplar view of the object. 8156955 1 P094105 sDeci lodae1/12 140 11170 180 100 0120 110 150 130 160 101 Fig. 1A 102 110 103ig. 1B Fig. 1C 110 Fg. -110 Fig. 1 D
