北方工业大学论文题目：基于直方图差值比较的人脸识别系统设计学生姓名：指导老师：学院：信息工程学院专业班级：电09A-1完成时间：2013年6月18日基于直方图差值比较的人脸识别系统设计摘要人脸识别系统因其在安全验证系统、信用卡验证、医学、档案管理、视频会议、人机交互、系统公安、罪犯识别等方面的巨大应用前景而越来越成为当前模式识别和人工智能领域的一个研究热点。本文提出了应用直方图差值比较的方法实现对人脸的识别。主要包括人脸的读入、人脸锁定、特征提取、人脸识别等四大模块。本文在总结分析人脸识别系统中几种常用的图像预处理方法基础上，利用MATLAB实现了一个集多种预处理方法于一体的通用的人脸图像预处理仿真系统，将该系统作为图像预处理模块可嵌入在人脸识别系统中，并利用灰度图像的直方图比对来实现人脸图像的识别判定。关键词：人脸识别；图像预处理；特征提取；直方图差值比较BasedonthehistogramdifferencecomparingthefacerecognitionsystemdesignAbstractBecauseFaceIdentificationhasgreatadvantagesinfrontssuchas;Securityverification,system,Credit,card,validation,medical,File,management,Videoconference,Thehuman-computerinteraction,Thepublicsecuritysystem,CriminalidentificationsoithasincreasinglybecomeaHotspotsinPatternrecognitionandArtificialintelligence.ThisessayusesHistogramdifferencecomparisonmethodtodistinguishFaceIdentification.Itcontainsfourmodules:Facereadingin,Facelock,FeatureextractionandFaceIdentification.WesummarizeandanalysisseveralusualTheimageprocessingmethods,andwealsouseMATLABtoachieveaFacerecognitionsimulationsystemwhichincludesAvarietyofprocessingmethods.ThesimulationsystemcouldbeembeddedintoFaceIdentificationsystem.WeuseGrayimagehistogramtorecognizefacesimage'sidentification.Keywords:Facerecognition,Imagepreprocessing,Featureextraction,Histogramdifferencecomparison.目录目录1.绪论.....................................................................................................................................-1-1.1研究背景..................................................................................................................-1-1.2人脸识别的应用前景..............................................................................................-2-1.2.1在安全防范领域中的应用...........................................................................-3-1.2.2在犯罪刑侦领域中的应用...........................................................................-4-1.2.3在公共事业领域中的应用...........................................................................-4-1.3人脸识别的概述......................................................................................................-4-1.4本文研究的问题......................................................................................................-5-1.5识别系统的构成......................................................................................................-6-1.6人脸识别国内外发展概况.......................................................................................-8-1.7现阶段人脸识别应用举例.......................................................................................-9-1.7.1数码相机人脸自动对焦和笑脸快门技术...................................................-9-1.7.2公安刑侦破案..............................................................................................-9-1.7.3门禁系统....................................................................................................-10-1.7.4摄像防盗系统...............
