摘　　要：以肌肉的控制量为基础,首先提出了一种面部运动的形式化描述方法,然后采用自顶向下的运动规划方法,对面部运动按时间、运动类型、奇点及控制量进行分割,获得面部运动单元.为了解决相邻动作单元之间不连贯的问题,根据他们之间的时间连接关系,采用不同的方法对动作进行'缝合'.最后设计了基于语义的嵌套式面部运动脚本,实现面部的复杂运动.实验表明,本文的方法能逼真、高效地实现连续、复杂的人脸面部运动.Based on muscle control items, a uniform model for facial action was constructed, which consisted of time series and the corresponding vector series. With the top-down motion planning, the facial action could be decomposed to motion unit by time, type of motion, singular point and control item. To solve the inconsistent problem of adjacent motion units, a joining algorithm was designed according to their relationship. Nested script of facial action was defined to implement the complex facial action. Experiments have shown that the methods can implement continuous and complicated facial action realistically and effectively.
