基于特征和弹性网格模型的快速人脸建模

为解决特定人脸的建模问题提供了一个简单而行之有效的方法。给定特定人脸的正面侧面照片，以及内嵌具有人脸特征信息的弹性人脸网格模型，采用基于小波分析的方法进行人脸特征识别，基于特定人脸的特征线相对于一般人脸模型上的特征线的位移，根据弹性系数求解所有点的位移变化，适配特定人脸几何。纹理映射之后生成能以任意视线方向观察的高度真实感特定人脸。该方法能在廉价的PC平台上快速而方便地得到实现。

Fast face modeling based on features and flexible mesh model

A simple but effective method is presented for realistically simulating particular human face. Provided frontal and side facial images and a general 3D polygonal facial mesh with face features, facial feature lines are fitted in the method based-on wavelet analysis. Based on relative displacement between the particular person's feature lines and the general model's feature lines, all the point's variations are performed to fit particular facial geometry. Then, after texture mapping, a virtual face is brought which can be observed in any direction and can make different expressions by combining different muscular vectors' motion. The method can be realized on PC plat easily and quickly.
