To obtain a video stream the camera, displayed in real time within the specified window the video 4. read a jpg file, its rotation, scaling, and then displayed)

这个是SIFT+RANSAC进行图像匹配的代码，代码中注释很详细，适合初学者，代码是C++版本的。SIFT算法用来提取特征，KNN距离比值法进行粗匹配，用RANSAC算法进行误匹配点的剔除 ，效果很好。

学生管理系统，可以添加删除，修改，是基于控制台的，挺好用的(student management system, can be added to delete, modify, is based on the console, very good use)

makefile编写手册。介绍得比较全面，担前面介绍太多概念，容易失去兴趣。最好还是该跳过时跳过。回头再看(Makefile write manual. To introduce it too is quite comprehensive, bear introduced too much in front of the concept, easy to lose interest. Still had better the jump out of date skip. Back to see )
