完整的PCA 人脸识别的应用包括几个步骤：人脸图像预处理；读入人脸库，训练形成 特征子空间；把训练图像和测试图像投影到上一步骤中得到的子空间上；选择一定 的距离函数进行识别-We present an approach to the detection and identification of human faces and describe a working, near-real-time face recognition system which tracks a s

用卷积神经网络（CNN）实现人脸识别，效果还可以，一个是training的程序，可以训练网络。一个是use程序，可以识别人脸(Using convolution neural network (CNN) to achieve face recognition, the effect is also available, one is the training program, can train the network. One is a use program that recognizes

基于opencv的简易人脸识别系统，完成了拍摄，训练模型，识别自己的脸的功能(A simple face recognition system based on OpenCV has completed the shooting, training model, and recognizes the function of the face.)
