基于MPEG-4的融合多元素的三维人脸动画合成方法

A Synthesis Method of Three-dimensional Facial Animation With Multiple Elements Blending Based on MPEG-4

为了实时合成真实感的可视语音,提出了一种融合口型、表情等多种运动元素的三维人脸动画合成方法.以MPEG-4人脸动画标准为基础,建立了汉语音节口型库和人脸基本表情库,通过在人脸动画参数上对共同影响面部运动的多种元素进行加权融合,合成出最终的动画序列.实验结果表明,该方法有效融合了面部运动的多种元素,同时具有真实感和实时性的优点.

In order to synthesize realistic visual speech in real time,this paper puts forward a new method for synthesizing three-dimensional facial animation, which blends dynamic elements of visual speech,facial expressions and other related factors.Based on the MPEG-4 facial animation standard,two databases are set up separately,including mouth shapes of Chinese syllable and basic human facial expressions.Then,a weighted average of facial animation parameters is introduced to affect facial movement,which represents variety of elements.Experiment results show that the method proposed in this paper effectively blends multiple elements of human face,receives realistic and real-time rendering facial animation.
