面部表情的仿真研究

Research on Simulation of Facial Expressions

随着ＣＧ技术的发展，人的身体形状和动作画像，可以通过电脑生成。人类逐步进入信息社会，人与机器的对话加入人物像后，可以使对话稳定和顺利进行，该文对人物面部表情的仿真，特别是自然、多彩的表情生成，从技术角度做进一步探讨。

A facial expression is defined by a time sequence of facial images. Various kinds of facial expressions can be generated from a basic facial image sequence by modifying the time generation functions. This paper describes a 3 D image generation method for facial expressions that uses three kinds of time generation functions. The facial expressions generated by these functions are compared and a method that breaks observed facial expressions down into these time generation functions is presented.
