本方法采用pca进行特征提取，knn分类器进行人脸识别。-The method of feature extraction using pca, knn classifier for face recognition.

利用完整局部二值模式（CLBP）特征提取方法，svm和knn分类器分类进行表情识别的matlab程序源码。并且附有CLBP论文-With a complete local binary pattern (LBP) feature extraction method, svm classifier classification and knn expression recognition matlab program source code. And paper with CLBP

使用了两种方法实现人脸识别：hog+svm，KNN(Two methods are used to implement face recognition: hog+svm, KNN)
