Abstract

In this paper, we propose a new tracking algorithm which uses weighted sum of color bin's centroids to find the main centroid of the target. The weights are determined by the proportion of colors of the target and by the colors of background. That is, A color which has high occupation in forming the target is highly weighted and a color which has low occupation is lowly weighted. Moreover, the proposed algorithm prevent track failure by lowering the weight of the colors which forms the background. Therefore, the proposed algorithm performs stable tracking inspite of occlusion and existence of confusing backgrounds.
