计算机科学与技术毕业论文--人脸识别技术综述 摘 要 随着社会信息化网络化得不断发展个人身份趋于数字化隐性化如何准确的鉴定确保信息安全得到越来越多的重视人脸识别一种应用比较广泛的生物识别方法在基于人脸固有的生物特征信息利用模式识别和图行图像处理技术来对个人身份进行鉴定在国家安全计算机交互家庭娱乐等其他很多领域发挥着举足轻重的作用能提高办事效率防止社会犯罪等有着重大的经济和社会意义 本文主要研究了人脸识别在图像检测识别方面的一些常用的方法由于图像处理的好坏直接影响着定位和识别的准确率因此本文对图像的一些识别算法做了着重的介绍例如基于二维Gabor小波矩阵表征人脸的识别算法基于模型匹配人脸识别算法等此外本文还提及了一般人脸识别系统的设计并着重介绍了图像预处理环节的光线补偿图像灰度化等技术使图像预处理模块在图像处理过程中能取到良好的作用提高图像识别和定位的准确率 [关键词]人脸识别 特征提取 图像预处理 光线补偿 Face Recognition Overview Abstract With the information society network was growing personal identity tends to digital hidden how to accurately identify to ensure that information security is more and more attention Face recognition an application of biometric identification methods more widely based on biometric facial information inherent in the use of pattern recognition and image processing techniques to map line of personal identity play a great role in the national security computer interaction family entertainment and many other areas Face recognition can improve efficiency prevent social crime of course it has significant economic and social significance  This paper studies aspects of face recognition in image detection and some common methods of identification As the image processing directly impact on the accuracy of location and identification so some of image recognition algorithm will be focused presentation such as Gabor wavelet-based two-dimensional matrix representation of face recognition algorithms model-based matching face recognition algorithm In addition the article also mentioned a general recognition system design and highlights the image preprocessing part of the light compensation gray image techniques the image preprocessing module in the image processing to get to the good and improve image recognition and positioning accuracy [Key Words] Face recognition feature extraction image preprocessing light compensation 目 录 1 前言 6 11 课题背景 6 com 人脸识别技术研究的背景[1] 6 12人脸识别技术研究的意义 6 13国内外现状与趋势 7 com 人脸识别的发展阶段[1
