README file for DALM/PALM and Homotopy l1-minimization code
by Victor Shia, Allen Yang
./paper目录 两篇有关Sparse Representation-based Classification(SRC)算法的原理
- PAMI-Face.pdf -> SRC原理
- YangA_ICIP2010.pdf -> SRC中涉及的L1-Min问题解法，包括DALM算法等
./codes目录 SRC算法具体实现
- slib静态库工程包括了SRC算法的主要实现，其中L1-Min问题使用的Fast DALM算法
- train exe工程实现了SRC的训练程序，使用见程序usage
- test exe工程实现了SRC的测试程序，使用见程序usage
- test.py文件(./codes/face_recog.SRC/_exe/test.py)实现了SRC算法的批处理测试功能
- ./codes/face_recog.SRC/_exe/extYaleB目录是extended Yale Face Database B人脸库
