Abstract: Presents a method to quantificationally measure expressions of virtual person by using MPEG4 standard and muscle-based facial model . Our method normalizes the moving parameters of facial muscles, then quantificationally measure expressions of virtual person. It provides a compact way to make animated person face or to construct a library of expressions.

Key words: face expressions, parameterize, muscle-based facial model, MPEG4

摘要: 本文描述了一种结合MPEG4标准和人脸肌肉模型对人类表情进行归一化定量描述的方法。该方法通过对人脸肌肉运动参数的归一化处理,实现了人脸模型表情的定量描述,为人脸动画制作和建立人脸动画表情库,提供了简洁的途径。
