使用神经网络进行脸部识别系统
应用背景介绍了人工神经网络(ANN)方法在数字图像识别中的应用,并通过在身份验证中的人面部特征提取与识别的实例对现有网络进行了研究,提出了改进思想,以期达到降低运算量、提高识别率的目的。关键技术应用神经网络技术构建了一个完整的人脸识别系统.首先使用基于眼睛位置估计的方法从人脸图像中分割出对识别有意义的纯脸,然后使用自组织映射进行特征压缩,提取有效的鉴别特征.最后使用基于知识的模糊神经网络进行分类.在NUSTDBII人脸数据库上的实验得到了令人满意的结果,并且表明该方法对人脸的姿态及表情有一定的不敏感性.

详细表述了分数阶傅立叶变换的离散实现,将现有的算法进行比较。-In this note we make a critical comparison of some matlab programs for the digital computation of the
fractional Fourier transform that are freely available and we describe our own implementation that lters
the best out of the existing ones. Two types of transforms are considered: First the fast approximate
fractional Fourier transform algorithm for which two algorithms are available. The method is described
in H.M. Ozaktas, M.A. Kutay, and G. Bozdagi. Digital computation of the fractional Fourier transform.
IEEE Trans. Signal Process., 44:2141{2150, 1996. There are two implementations: one is written by
A.M. Kutay the other is part of package written by J. O Neill. Secondly the discrete fractional Fourier
transform algorithm described in the master thesis C . Candan. The discrete fractional Fourier transform,
Bilkent Univ., 1998 and an algorithm described by S.C. Pei, M.H. Yeh, and C.C Tseng: Digital fractional
