基于pca+lda+粗糙集+模糊神经网络的人脸识别程序
pca+lda+粗糙集+模糊神经网络saveORLimage.m将ORL人脸库分为测试集ptest和训练集pstudy存为imagedata.mat1.savelda.m将人脸库先进行pca降维，再用lda进行特征提取，得到新的测试集ldatest和训练集ldastudy存为imageldadata.mat2.对ldastudy进行离散化(discretimage.m)，得到离散化矩阵disdata,存入到imagedisdata.mat3.将disdata组成决策表(savers.m)，通过对disdata的条件属性进行约简，得到其一个约简，组成新的测试集rstest和训练集rss
