经典的Harris角点检测算法经过改进的VC代码，可以用来提取灰度图象的特征点，用于匹配，运动估计，光流计算，形状分析等。-classic Harris corner detection algorithm improved VC code, Gray can be used to extract image feature points for the match, motion estimation, optical flow, shape analysis.

matlab程序。利用二维图像生成3d形状，有原始代码，有测试数据。(We investigate the problem of estimating the 3D shape of an object, given a set of 2D landmarks in a single image.To alleviate the reconstruction ambiguity, a widely-used approach is to confine the unknown 3D shape
