1 简介
为了解决计算机信息技术发展带来的商业贸易方面的安全问题,生物识别(特别是人脸识别技术)在商业贸易中起了重要的应用.本文通过设计基于高斯模型的人脸识别系统,采用图像转换计算相似度,采用A(CB,CR)计算颜色空间,肤色模型使用高斯模型进行人脸识别,基于先验知识进行二值化采用阈值分割法,采用水平方向,垂直方向投影等进行人脸定位,利用几何特征提取信息进行人脸检测.基于高斯模型的人脸识别系统能够满足用户对面部特征识别的需求,为移动支付、系统安全等场合提供良好的解决方法.
2 部分代码
function varargout = untitled(varargin)
% UNTITLED MATLAB code for untitled.fig
% UNTITLED, by itself, creates a new UNTITLED or raises the existing
% singleton*.
%
% H = UNTITLED returns the handle to a new UNTITLED or the handle to
% the existing singleton*.
%
% UNTITLED('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in UNTITLED.M with the given input arguments.
%
% UNTITLED('Property','Value',...) creates a new UNTITLED or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before untitled_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to untitled_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
