多元线性回归算法，能将多个线性的物质之间的变量和自变量之间建立相关度高的线性回归方程。(Multiple linear regression algorithm, can the variables and between multiple linear material to set up linear regression equation with high correlation between independent variables. )

对一幅数字图像采用理想低通、Butterworth低通 、Gaussian低通滤波器进行平滑；对一幅数字图像采用理想高通、Butterworth高通 、Gaussian高通滤波器进行平滑。 (The ideal of a digital image using low pass, Butterworth low-pass, Gaussian smoothing low pass filter on a digital image using the ideal high-pass, Butterworth high-pass, Gaussian high-pass filter smoothing. )

该matlab程序是自己编的，生成一组亚像素位移低分辨率图像，用于验证亚像素匹配或超分辨率重建。(get low resolution image of subpixel shift,used for image registration or Image Super-Resolution)

the fast autocorelation function matlab code, used for basicallly pitch extraction and thus is extremely useful
