含有 SIFT 的c代码（基于OPEN CV) 和一份程序解说 ppt。 经过多方求取，学习，发现这是目前学习 sift 算法细节最有用的2份资料了，c 代码虽然是基于 open cv 的，但是不影响对 sift 算法整个流程的展现，只用到 openv 中对图像操作的部分，完全可以修改成纯 VC ++ 的代码哦~~ -SIFT contains the c code (based on OPEN CV) and a procedural explanation ppt. After many seeking, learning, discovery learning sift algorithm This is the details of the most useful information a 2, c code though is based on open cv, but does not affect the sift algorithm show the whole process, only used on images openv operation part, can modify to pure VC++ code oh ~ ~
