SIFT发明人LOWE的SIFT特征提取程序代码及执行文件，用于图像特征点识别和图像拼接等。-LOWE inventor SIFT SIFT feature extraction program code and executable file for image feature point recognition and image stitching.

基于vs2010+opencv2.4.9的两张图像拼接，利用sift进行特征点提取，借鉴rob_hess源代码。-This algorithm achieved two images stitching ,basing on sift algorithm
