数字图像处理课程设计论文 题  目：人脸识别中图像预处理方法的研究 学  院：  计算机学院 专业名称： 计算机应用技术 学  号： 20078783939 学生姓名： 指导教师：  张胜男 刘亚 2010 年 6 月 29 日 黄石理工学院数理学院 摘  人脸识别中图像预处理的研究 张胜男 ，湖北 黄石，435000 要：本设计是一个关于人脸识别图像预处理的研究,人脸识别技术是计算机模式识 别研究领域中一项热门的研究课题，它属于生物特征识别技术，是对生物体(一般特指人) 本身的生物特征来区分生物体个体，在军事、银行、机关等部门有着广泛的应用前景。本 文主要对人脸图像进行预处理，以便为进行下一步的图像识别做前提准备。文中首先我们 会认识一下什么是人脸识别，它的优势、不足、目前的发展以及以后的前景。什么是预处 理、预处理有哪些方法以及怎样进行预处理。文中对各种预处理法及其在人脸识别中的应 用作了详细的介绍，并对各种方法从理论分析和实验结果两方面进比较，从而让人们对人 脸识别图像预处理有更深一层的了解。本文针对光照对人脸图像的影响还提出了同态滤波 的方法。 关键词：生物技术；人脸识别；图像预处理；同态滤波 Face Recognition In the Image Of Pretreatment Huang FangYong School of Mathematics and Phusics,Huangshi Institute of Technology,Huangshi 435000,China Abstract:  The design is an image on the pretreatment of face recognition, face recognition technology is the computer pattern recognition research in the field of a hot research topic, it belongs to the biometric identification technology, the organisms (specifically people in general ) Their biological characteristics to distinguish between individual organisms, in the military, banks, agencies and other departments have broad application prospects. In this paper, the face image preprocessing, the next step in order to carry out the image recognition premise prepared to do. In the first we will understand what is face recognition, its advantages, less than the current development and future prospects. What is the pretreatment, which pretreatment methods and how to pretreatment. Text of the law and its various pretreatment in the application of face recognition in detail, and various methods from the theoretical analysis and experimental results to compare the two areas so that people on the face recognition have a better image of a pretreatment Of understanding. This paper light on the impact of human face images with the state also proposed a filtering method.
