Towards talking face on portable devices - a flexible and realistic approach

Talking face using face modeling and animation techniques has been a popular branch of computer graphics for several years. There are many methods of texture mapping to obtain realistic result, or produce natural animation. In this paper, we propose a flexible texture mapping method aiming at application on portable devices. Our method needs only one single front view face image and it does not require exact match between the model and the presented texture. Satisfactory mapping can be achieved by interactive adjustment scheme, where users define correspondence for feature locations through editing the key points and their influence regions. Efficiency and realism are well balanced using our algorithm.
