Description: 摘要：主成分分析（PCA）的人脸识别算法，以减少的特征向量是涉及到对抽象的特点，改进了主成分分析（一）iUumination算法的变化影响酶原sed.The方法是基于上减低与正常化其相应的标准差的特征向量元素相关联的大特征值的特征向量的影响力的想法。耶鲁大学和耶鲁大学面临的数据库面对数据库B是用来验证-Abstract：In principal component analysis(PCA)algorithms for face recognition，to reduce the influence of the
eigenvectors which relate to the changes of the iUumination on abstract features，a modified PCA ( A)
algorithm is propo sed．The method is based on the idea of reducing the influence of the eigenvectors associated
with the large eigenvalues by normalizing the feature vector element by its corresponding standard deviation．
Th e Yale face database and Yale face database B are used to verify the method．The simulation results show
that，f0r front face and even under the condition of limited variation in the facial po ses the proposed method
results in better perform ance than the conventional PCA and linear discriminant analysis(LDA)approaches．and
the computational cost remains the same as that ofthe PCA，and much less than that ofthe LDA．

recognition(FR)system．Linear Discriminant Analysis(LDA)is one of the most popular linear classification techniques of

Description: 人脸识别技术是计算机模式识别领域非常活跃的研究课题，在法律、商业等领域有
着广泛的应用前景。自动人脸识别系统一般由两个模块组成：定位与检测模块，特征提
取与识别模块。本文对两个子模块进行了详细讨论，通过实验仿真了一个基于静态图像
的人脸识别系统。为提高系统的识别率，本文对定位检测模块和特征提取模块进行了深
入研究。
针对复杂多变人脸检测和定位问题，实现了一种基于对称特征的人脸定位方法。该
算法首先基于肽色特征提取出人脸区域，根据眼睛的颜色和梯度特征在肤色区找到眼睛
可能存在的有限的候选区域：根据人脸的对称特征，把这些候选区域分别进行匹配，找
到最佳匹配的区域就是眼睛区域。本算法适用于表情变化，姿态变化，有胡须，戴眼镜
的多种情况。特征提取是人脸识别系统中非常重要的技术，本文仿真的人脸识别系统采
用一种结合主元分析(PCA)和F．LDA的人脸识别方法。为了解决F．LDA直接应用到
高维模式识别中计算复杂度太大的问题，算法中首先应用主元分析进行降维。该算法能
克服LDA的小样本问题。-ne technology of face recognition is all active subject in the area of pattern recognition．
There are broad applications in the fields of law，business ere．A face recognition system
includes two parts：face detection and localization．feature extraction and classification,which
are discussed in detail．A face recognition system based on static image is simulated．In order
to improve the recognition rate，a new face detection and localization method and a new
feature extraction method are proposed．
