3.3 匹配与识别
人脸人别系统的最后一步是人脸识别。人脸识别，即通过对所采集到的人脸图像进行一系列处理，提取待识别人脸图像的特征信息，通过与已存人脸数据库信息进行匹配识别，确定待识别人脸图像的基本信息。运行如下代码：
function varargout = faceCore(varargin) % FACECORE M-file for faceCore.fig
% FACECORE, by itself, creates a new FACECORE or raises the existing
% singleton*. %
% H = FACECORE returns the handle to a new FACECORE or the handle to
% the existing singleton*. %
% FACECORE('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in FACECORE.M with the given input arguments.
%
% FACECORE('Property','Value',...) creates a new FACECORE or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before faceCore_OpeningFunction gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to faceCore_OpeningFcn via varargin.
