SIFT算法的主要实现，对一些不容易注意的点进行了学习和分析，有助有更好的了解SIFT-The main achievement of SIFT algorithm is not easy to pay attention to some points of the study and analysis will help a better understanding of SIFT

sift matlab实现。绝对好用！！！！(Sift matlab implementation. Absolutely easy to use!!!!)

非常好用，可以提取两幅图像的同名点，匹配，配准，一整个流程，都可以实现，代码注释易懂，简单易学(Very useful, can extract two images of the same name points, matching, registration, a whole process, can be achieved, code annotations easy to understand, easy to learn)

基于SIFT的图像匹配配准，代码亲测好用，注释简单易懂，可以提取同名点，进行匹配配准。(Based on SIFT image matching registration, the code is easy to use, the annotation is simple and easy to understand, and the same name points can be extracted for matching registration.)
