人脸建模和动画的基本技术

文中讨论了通过人脸的正向和侧面照片构造头部的三维模型，并赋予其简单动画的基本技术，基于此技术，实现了一个交互式人脸建模和动画的工具，详细阐述了在系统实现过程中应用到的人脸几何表示，由一般人脸变化到特定人脸，弹性网格，肌肉模型，关键,帧和表情提取等技术。

The Kernel Techniques in Face Modeling and Animation

The kernel techniques of constructing a 3D model of human head from front and side photos of a specific person and then realizing its simple animations are discussed. The authors have developed an interactive face modeling and animation tool based on these techniques. This paper gives a detailed introduction to the techniques, including polygonal representation for surface, deformation from a generic face model to a specific model, spring mesh, muscle based animation model, key frame animation technique and expression extraction technique.
