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

几种矩阵是仿射变换经常用到的矩阵，在实际应用中非常重要。PV项目中，我们用到的参数是affine六次元，但经过和变换矩阵的映射，可以转换为上面更为常用的仿射变换Matrix，这样就可以用相关的图形或图象库来实现图象的变换-Several above affine transformation matrix is often used in the matrix, is very important in practical applications. PV project we used par
