Description: 现有的代数特征的抽取方法绝大多数采用一维的方法，即首先将图像转换为一维向量，再用主分量分析（PCA）,Fisher线性鉴别分析（LDA）,Fisherfaces式核主分量分析（KPCA）等方法抽取特征，然后用适合的分类器分类。针对一维方法维数过高，计算量大，协方差矩阵常常是奇异矩阵等不足，提出了二维的图像特征抽取方法，计算量小，协方差矩阵一般是可逆的，且识别率较高。-existing algebra feature extraction method using a majority of the peacekeepers, First images will be converted into one-dimensional vector, and then principal component analysis (PCA), Fisher Linear Discriminant Analysis (LDA), Fisherfaces audits principal component analysis (KPCA), and other selected characteristics, then use the appropriate classification for classification. Victoria against an excessive dimension method, calculation, covariance matrix is often inadequate singular matrix, a two-dimensional image feature extraction method, a small amount of covariance matrix is usually reversible, and the recognition rate higher.

Description: 这是一个lda的程序，在别处找到的，觉得还行，想和大家分享分享。识别率确实不错，我实在orcl人脸库上进行的，在其他的人脸库里还未来得及试验，相信也会很不错的。大家多多支持啊。-lda This is a procedure in finding elsewhere, I felt that trip, and would like to share with you to share. Recognition rate is not bad, I really orcl people on the face of the other person has not yet time to face 13-17 test believe will be very good. Members can support ah. Platform: |

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

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
