| 摘 要： | 对于人脸视频中的每一帧,提出一种静态人脸表情识别算法,人脸表情运动参数被提取出来后,根据表情生理知识来分类表情;为了应对知识的不足,提出一种静态表情识别和动态表情识别相结合的算法,以基于多类表情马尔可夫链和粒子滤波的统计框架结合生理知识来同时提取人脸表情运动和识别表情.实验证明了算法的有效性.

| Abstract: | For each frame in the facial video sequence,an algorithm for static facial expression recognition is proposed firstly,facial expression is recognized after facial actions are retrieved according to facial expression knowledge.Coping with lacking of knowledge,an algorithm combining static facial expression recognition and dynamic facial expression recognition is proposed,facial actions as well as facial expression are simultaneously retrieved using a stochastic framework based on multi-class expressional Mar... |
