SIFT是一种非常热门的图像匹配算法，能对发生旋转、缩放的图像进行匹配，文件演示了匹配过程，用MATLAB给出了源代码-SIFT is a very popular image matching algorithm, can occur rotating, zooming, image match, the document demonstrated the matching process, using MATLAB source code is given

SIFT算法的使用demo，对自己编程序很有帮助，是对图像分析的好帮手。-SIFT algorithm for the use of demo, programmed to their helpful, image analysis is a good helper.

sift初学者，不是很有见地，需要学习的还是很多，希望多给意见-sift beginners, not very insightful, study or required a lot of hope to the many views

SIFT算法的相关实现 自己用matlab写的sift特征点检测与匹配程序，运行能通过-SIFT algorithm related to realize their written with matlab sift feature point detection and matching program, run through
