| 摘 要： | 通过三维变换的特征点搜索方法对二维人脸图像进行形状搜索，形状搜索以人脸的标准三维模型为基础，将二维坐标三维化；通过三维变换、投影等过程迭代搜索逼近目标形状，最后得到三维变换的10个姿态参数。测试结果表明：在对非活动形状模型(ASM)训练集中的多姿态人脸进行形状搜索时，三维变换方法具有更好的逼近效果。较好地模拟了人脸姿态的实际变化，有效地解决了ASM人脸偏转的非线性问题。

| Abstract: | Through three-dimension(3D)transformation shape search on two-dimension(2D)face image,the variation of the face gesture can be simulated correctly,and the nonlinear variations of face on Active Shape Model(ASM)are solved effectively.Based on standard face 3D model,the three-dimension coordinates were gotten by 2D initial shape;and 10 gesture-parameters of 3D transformation were calculated through the iterating process of 3D transformation,projecting to track the object shape.The test data show the 3D transf... |
