不论科研还是应用上都希望可以和人类的视觉一样通过程序自 动找出两幅图像里面相同的景物，并且建立它们之间的对应，前几年才被提出的SIFT（尺度不变特征）算法提供了一种解决方法，通过这个算法可以使得满足一 定条件下两幅图像中相同景物的某些点（后面提到的关键点）可以匹配起来-Both research and application, or want to be like the human visual images by automatically identifying two inside the same scene, and the establishment of the correspondence between them, a few years ago was only made by SIFT (scale-invariant features) algorithm to provide a solution by this algorithm can make to meet certain conditions, the same two images, scene of some point (later referred to the critical point) can match the相关搜索： sift
