图像局部不变量特征提取和描述子，pdf文档-Local invariant feature extraction and descr iptor, pdf documents

是一种局部特征描述子，计算速度比SIFT和其他局部特征比较快。-local feature descr iptor

用C++实现的自相似性描述的源代码（matlab包装）用来特征提取特征侦测等。-C++ Implementation (with MATLAB wrapper) of the Self-Similarity Descr iptor by Ken Chatfield based on the paper Matching Local Self-Similarities across Images and Videos, by Eli Shechtman and Michal Irani at CV

Locality-constrained Linear Coding (LLC) in place of the VQ coding in traditional SPM. LLC utilizes the locality constraints to project each descr iptor into its local-coordinate system, and the projected coordinates are integrated by max pooling to
