We present a method to match the silhouettes obtained from the video sequence and the image projection from a computer generated virtual 3D human model. By adjusting the 3D pose of the virtual 3D model iteratively based on the kinematic constraints of human motion and skin color detection, the human pose and the associate 3D motion parameters can be uniquely identified and the self-occlusion problem can be refined.
