%X We present a statistical model-based video segmentation algorithm for typical videophone and videoconference applications. This algorithm makes use of on-lineinformation and tries to build statistical models for both background and foreground and update the models on the y. A hierarchical system structure is designed and segmentation is combined with tracking. Two possible applications are discussed: to generate VOP for MPEG-4 and to introduce subjective rate control for DCT-based algorithms. A R-D based rate control algorithm for H.263 is proposed and implemented as an example
