1、 毕毕 业业 设设 计计 论论 文文 题 目： 基于 MATLAB 的人脸识别系统设计 学 院： 电气与信息工程学院 专 业： 自动化 I 摘要 人脸识别是模式识别和图像处理等学科的一个研究热点，它广泛应用在身份 验证、刑侦破案、视频监视、机器人智能化和医学等领域，具有广阔的应用价值 和商用价值。人脸特征作为一种生物特征，与其他生物特征相比，具有有好、直 接、方便等特点，因此使用人脸特征进行身份识别更易于被用户所接受。 人脸识别技术在过去的几十年得到了很大的发展，但由于人脸的非刚性、表 情多变等因素，使得人脸识别技术在实际应用中面临着巨大的困难。本文针对近 年来国内外相关学术论文及研究报告进行
2、学习和分析的基础上，利用图像处理的 matlab实现人脸识别方法，这种实现简单且识别准确率高，但其缺点是计算量大， 当要识别较多人员时，该方法难以胜任。 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： 图像处理, Matlab, 人脸识别, 模式识别 河南城建学院本科毕业设计（论文） ABSTRACT II ABSTRACT Human face recognition focuses on pattern recognition ,image
