The method can integrate the facial animation parameters of MPEG-4 into action unit adjuster and get realistic effect easily. 该方法可使得MPEG-4脸部动画参数容易映射到动作单元调节器上,比较真实地表现脸部表情动作。
MPEG-4 Facial Animation Parameters(FAP) and Muscle-Model for Sequence Rendering MPEG-4中脸部动画参数和序列重绘的肌肉模型
In order to drive the animation of facial models more efficiently, two high-level methods are proposed, one is based on FAP ( facial animation parameters ) stream of MPEG-4 standard, and the other is based on muscle model. 为了简化人脸模型的驱动,提出了基于MPEG-4中脸部动画参数FAP(facialanimationparameters)流和基于肌肉模型的两种高层驱动方法。
Then the template is used to estimate the facial animation parameters, which is converted to FAP compatible with MPEG-4 and compressed later. 另外,利用点匹配法跟踪相邻帧特征点的位移,估计头部整体运动参数。并将这些参数转化为符合MPEG-4标准的FAP,进行压缩。
The system could produce high realistic facial animation from decoded parameters on decoder. 该演示系统可在解码端根据解码后的参数合成真实感的人脸动画。
