Tracking and recognizing non-rigid objects in video image sequences are complex tasks of increasing importance to many applications. In this paper, we present a hierarchical realization of an enhanced active shape model for color video tracking and we study the performance of hierarchical and non-hierarchical implementations in the RGB, YUV, and HSI color spaces.
