说明：  两个adaboost算法，代码很短，都有中文注释，第二个代码是第一个的改进。(Two algorithms about adaboost ,the code is very brief,including the Chinese comments. The second one improver better than the first one.)

this is a good program for beginner

稀疏表示经典著作 John Wright et al, Robust Face Recognition via Sparse Representation , PAMI 2009的程序(# impFaceRecognition A Matlab implementation of Face Recognition using Sparse Representation the original paper: John Wright et al, Robust Face Recognition via Sparse Representation , PAMI 2009. In our implementation, we propose a Multi-scale Sparse Representation to improve the performance compared to the original paper. If you use our code, please cite the paper: Multi-scale Sparse Representation for Robust Face Recognition )
