一种主元分析的人脸识别matlab源码，利用SVD分解提取主分量进行人脸识别(A principal component analysis for face recognition matlab source code, the use of SVD decomposition to extract principal components for face recognition)

基于matlab的图像采集与处理系统源码。利用MATLAB软件做出一个可操作的图形化界面，该界面能实现对图像的实时采集、后续图像的处理、图像的保存，帮助使用者对实验现象进行实时采集分析。(Matlab-based image acquisition and processing system source code. Using MATLAB software to make a workable graphical interface that enables real-time image acquisition, preservation subsequent image processing, image, and help users to perform real-time acquisition and analysis experimental phenomena.)

eof分解用的函数，说明如下：function [EOF,PC,F,diff]=EOFcgx(X) EOF分解。Xm*n 空间数据维数m，n为时间采样点 返回值EOF为空间模态,PC为时间模态。第一空间模态EOF(:,1),第一时间模态PC(1,:) 返回值F为特征值，diff为误差 (eof decomposition function as follows: function [EOF, PC, F, diff] = EOFcgx (X) EOF decomposition. Xm* n spatial dimension m, n is the time of sampling points Returns the value EOF spatial modes, PC is the time modes. The first space modal EOF (:, 1), the first time the modal PC (1, :) Return value F for eigenvalues, diff for error )
