【人脸识别】基于FISHER线性判决实现人脸识别含Matlab源码

1 简介

人脸识别是生物特征鉴别技术的一个主要方向,与其他生物特征相比,人脸识别具有主动性,非侵犯性和用户友好等许多优点,多年来一直受到许多研究者的关注.从最初的基于几何的方法到基于统计等复杂特征的方法,人脸识别已经发展了很多算法.目前基于统计特征的线性方法在人脸识别中发展的比较成熟,但是由于人脸识别涉及光照,表情,姿态等问题,线性方法在实际应用中表现的远远不够.因此,将线性方法拓展到非线性领域以提高识别率是一个亟待解决的问题.

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.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
