The dissertation focuses on the following three aspects : MPEG-4-based facial action coding system, text driven facial animation and speech driven facial animation, which have always been challenges in computer vision and computer graphics. 本文的工作包括三个方面:基于MPEG-4标准的面部动作编码、中文文本驱动的人脸动画、连续汉语语音驱动的人脸动画,他们也一直是计算机视觉和计算机图形学中一直具有挑战性的研究课题。
Research in this dissertation includes the recognition of six basic expressions from static images with mixed facial expressions, and the analysis of dynamic image sequence according to facial action coding system. 本文的研究包括了人脸表情静态图像的表情基本类别识别,以及动态人脸表情图像序列的表情运动单元识别,也就是表情的自动分析。
The robot body could realize the movement of eyeball, eyelid and lip. The facial expression and basic lip shape of robot were realized by controlling the movement of feature points in the flexible skin based on facial action coding system ( FACS ). 机器人本体实现眼球、眼睑、下颚等部件运动,基于面部表情编码系统(FACS),通过控制柔性皮肤上的特征点运动实现机器人的面部表情和动态口形。
