| 摘 要： | 提出了一个基于彩色照片的个性化人脸建模的新方法。根据MPEG-4确定出标准模型特征点的位置，从正面和侧面两幅照片出发，首先进行了这两幅彩色图像人脸边缘特征提取，接着定位进行特征点编辑，获取人脸的关键特征点的位置，然后对标有对应特征点的标准模型进行变形，进行纹理映射，最后获得了真实的个性化人脸模型，两张照片可以合成任意角度视图。以该方法建立的人脸模型精度比较高，可以快速地建立个性化人脸模型，为三维人脸动画提供了真实模型。

| Abstract: | In this paper, a method of 3D facial modeling based on color photos is presented. According to MPEG - 4, we affirm feature points on the general model, we make out color edge features, then edit feature points on two perpendicular images, and obtain key feature points of human face, then deform the general model and go along texture mapping, at last get a realistic individual model. Arbitrary views can be generated from the two pictures. The experiment results demonstrate that our algorithm is a better accuracy, quick one, which provides a realistic model for human face animation. |
