This paper presents a real-time 3D face animation system driven by contour-based visual tracking. First, a 2D contour-based tracking algorithm is applied to track the lips. Three different algorithms are proposed to infer the 3D deformation of the lower face from the tracking results. The 3D deformation information is then used to animate a 3D face model. The system is implemented on a mid-level PC and it runs at 30fps. The system can be used to realize a very low bit rate videophone system. For the purpose of model-based picture coding, this system complements contemporary media transform techniques that convert text or speech to visual information.
