Abstract :
In this paper, we propose a body animation parameter (BAP) generation system for global head movement using head motion analysis and tracking. The proposed system consists of two separate layers: head motion analysis layer and 3-D model registration layer. Following the MPEG-4 SNHC standard, we generate the global head motion using body definition and animation parameters. In the implemented system, we acquire head motion data from a single camera and extract body definition parameters from an arbitrary VRML human model.
