马氏距离的仿射不变性删除误匹配特征点 对，据此可求取2幅源图像间的仿射变换参数-Mahalanobis distance of the affine invariant features remove the false matching points Yes, according to the source to obtain two parameter affine transformation between images

一个演示如何使用“LineMatcher”库的示例,该库用于生成仿射不变匹配直线。详细算法参考Bin Fan, Fuchao Wu and Zhanyi Hu. Line Matching Leveraged by Point Correspondences, In CVPR 2010, pp 390-391. 示例中基于opencv2.2获取匹配点，系统配置为 Win 7 32bits + VS2010 realese -A demonstration of how to use the

spd描述子，ACO算法匹配，文件中包含其他的描述子（形状上下文。。。），同时距离函数包括欧式距离和卡方距离(The SPD descr iptor matches the ACO algorithm, and the file contains other descr iptors (shape context) At the same time, the distance function includes Euclidean distance and chi square distance
