基于PCA与SVM的人脸识别matlab代码

基于PCA与SVM的人脸识别系统，用matlab编写，我测试过了！

function nClass = classify（newFacePath）
% 整个分类（识别）过程

display（‘ ‘）;
display（‘ ‘）;
display（‘识别开始...‘）;

% 读入相关训练结果
display（‘载入训练参数...‘）;
load（‘Mat/PCA.mat‘）;
load（‘Mat/scaling.mat‘）;
load（‘Mat/trainData.mat‘）;
load（‘Mat/multiSVMTrain.mat‘）;
display（‘..............................‘）;

xNewFace = ReadAFace（newFacePath）; % 读入一个测试样本
xNewFace = double（xNewFace）;
xNewFace = xNewFace*W; % 经过pca变换降维
xNewFace = scaling（xNewFace1A0B0）;


display（‘身份识别中...‘）;
nClass = multiSVMClassify（xNewFace）;
display（‘..............................‘）;
display（[‘身份识别结束，类别为：‘ num2str（nClass） ‘。‘]）;
