基于机构学和肌肉模型的单视频驱动人脸情感表达仿真
摘 要
描述一种3维人脸模型的单视频驱动方法。该方法在传统肌肉模型的基础上，根据嘴部运动特性采用机构学原理建立嘴部运动控制模型，通过视频图像序列跟踪得到特征点的运动规律曲线，进而驱动眼部、嘴部及面部其他部分的网格点运动，产生具有真实感的面部表情动作。仿真结果表明，采用此方法可以得到逼真的人脸表情模拟动画。

Drive facial animation by using single video based on the mechanism theory and muscle model
() Abstract
A method to drive 3D facial model using single video was presented. Based on the movement characteristics, the mouth was controlled by using a mechanism model. The motion trace of the feature points was acquired by tracking video image sequence. Then we drive the grid nodes on the facial model to obtain a realistic facial animation. The results show that this method could simulate the facial movements and expressions very well.
