【模式识别】银行监控系统之人脸识别【Matlab 096期】
一、简介
用matlab做的多人场景的人脸识别。先预处理，人脸定位，分割，训练，PCA降维求出协方差矩阵，人脸特征值，然后每个测试的人脸分别进行矩阵求列，作差对比，结果最小的就是目标人脸，输出识别结果，这个设计有可视化GUI用户操作界面。
二、源代码
function varargout = Main(varargin)
% MAIN MATLAB code for Main.fig
% MAIN, by itself, creates a new MAIN or raises the existing
% singleton*.
%
% H = MAIN returns the handle to a new MAIN or the handle to
% the existing singleton*.
%
% MAIN('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in MAIN.M with the given input arguments.
%
% MAIN('Property','Value',...) creates a new MAIN or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before Main_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to Main_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
%
% See also: GUIDE, GUIDATA, GUIHANDLES
