RANSAC算法，可以滤除SIFT的误匹配，在计算机视觉领域应用广发。-RANSAC algorithm, can filter out erroneous SIFT matching applications in the field of computer vision GF.

用c++实现sift特征点的检测，匹配，并用RANSAC滤除掉误匹配点，在VC2008运行效果不错。-With c++ achieve sift feature point detection, matching, and filtered out using RANSAC mismatching points, the VC2008 run good results.
