光学图像的空间滤波，低通滤波可略去高频，通过低频。(lowpass filter)

lle算法主要程序，运用的KNN邻近分类器，其中也含有均衡化的程序(LLE algorithm)

图像的稀疏表示，用小波系数经过的构造的矩阵稀疏化后，用少数的系数表示图像。(Image sparse representation, constructed after the matrix of wavelet coefficients after thinning, with a small number of coefficients represent the image.)

数据整理，数据和标签和样本数量之间的匹配，当然也可以用其他方法，仅供参考(Data collation, matching between data and label and sample quantity, of course, other methods can be used, for reference only)

说明：  PLS、BP、SVR代码，参数可调，修改后可用，也可为学编程的同仁提供参考。(PLS, BP, SVR codes, adjustable parameters, can be used after modification, and can also provide reference for colleagues learning programming.)
