编程是由pca和lda结合的脸部特征提取，用于三维图像。-multilinear principal component analysis combined with Linear discriminant analysis 3D face feature extraction.

LDA（线性判别分析）程序，给大家参考一下啊-LDA (linear discriminant analysis) program, for your reference.

airpls扣掉原始数据荧光背景，pls提取主成分，lda进行线性判别分析。程序和数据完整，不懂欢迎询问(Airpls's original data of fluorescence background, pls principal component extraction, linear discriminant analysis. Program and data integrity, welcome to inquire)
