这是SIFT和SURF算法的基本介绍的文档，初学者可以快速入门，对匹配算法快速掌握。-SIFT and SURF algorithms which is a basic introduction to the document, beginners can get started quickly, right matching algorithm to grasp.

基于opencv的 orb特征点匹配的算法实例 比sift suft快很多-Opencv orb feature points matching algorithm instance is much faster than sift suft

基于SUFT的特征提取与匹配，内涵详细的文档说明，很好的实现了特征提取与匹配，该方法较基本的SIFT有很大的提高-Extraction and matching of features based on SUFT, detailed content of the documentation, very good realization of the feature extraction and matching, SIFT the method is basic is greatly impro
