D.G lowe 的尺度不变特征转换算法（SIFT）在基于opencv和OpenGL的源码基础上增加了图像的保存功能。用于对图像的尺度不变特征的提取以及图像特征点的匹配-D.G lowe s scale invariant feature transform (SIFT) algorithm based on opencv and on the basis of OpenGL source to increase the function of image preservation. Used

特征提取，主要是灰度共生矩阵和不变矩特征提取的程序，openCV下可直接运行-Feature extraction, mainly GLCM and invariant moments feature extraction procedures can be run directly under openCV
