Description: 数据降维算法
K_L变换是一种最优正交变换，以矢量信号X的协方差矩阵Ф的归一化正交特征矢量q所构成的正交矩阵Q，来对该矢量信号X做正交变换Y=QX，则称此变换为K-L变换（K-LT或KLT）。-Data reduction algorithm K_L optimal orthogonal transform is a transformation to vector signal covariance matrix Ф X normalized orthogonal feature vector composed of q orthogonal matrix Q, to be orthogonal to the vector signal X transformation Y = QX, called the KL transform transform (K-LT or KLT).

Description: 基于KL变换的特征提取的方法。
选取数据库中的部分样本（每个人的前5张图片）作为训练样本，其余作为未知的测试样本。从训练样本中得到KL变换矩阵，然后对训练样本和测试样本都进行变换，用变换后的数据作最近邻识别，距离可以为对应灰度值之差的平方和，统计识别率。-KL transform based feature extraction method. Select the database part of the sample (each person' s top 5 pictures) as the training samples, the rest as unknown test samples. Training samples obtained from KL transform matrix, then the training samples and test samples for transformation, with the transformed data for the nearest neighbor recognition from the corresponding gray value for the difference of squares, statistical recognition rate.
