近红外光谱小波变换预处理方法，能将信号分解成一系列小波函数的叠加，这些小波函数都是由一个亩小波函数平移和伸缩得到的。-Near infrared spectra pretreatment method, wavelet transform signal can be decomposed into a series of wavelet function, the wavelet function is a function by a mu wavelet translation and sca

提升的9/7小波变换，用于处理一维或二维的灰度图像-9/7 lifting wavelet transform, processing one-dimensional or two-dimensional gray-scale image is used
