Abstract

We propose a dominant-feature based matching method for capturing a target in a video sequence through the dynamic decomposition of the target template. The target template is segmented via intensity bands to better distinguish itself from the local background. Dominant feature elements are extracted from such segments to measure the matching degree of a candidate target via a sum of similarity probabilities. In addition, spatial filtering and contour adaptation are applied to further refine the object location and shape. The implementation of the proposed method has shown its effectiveness in capturing the target in a moving background and with non-rigid object motion.
