This paper proposes a system for tracking a single target in images based mainly on color and on motion as an auxiliary information. The target we want to track is commonly not necessarily conspicuous in color, and often exists in close proximity to other similar objects. Thus, we should discriminate the target from distractors which closely resemble the target in color feature. Assuming the target and distractors differ in motion, and evaluating the likelihood of distractors based on the optical flow information in the vicinity of the target, we can distinguish the target smoothly from the background scene. An experiment for tracking a moving hand in front of a human face confirmed the feasibility of the proposed system. The results demonstrate the validity of our approach.
