在matlab中实现峰值信噪比的函数 function y=psnr(im1,im2) 计算峰值信噪比程序——————————————— - ininput im1 : the original image matrix (For peak signal to noise ratio in matlab function function y = psnr (im1, im2) calculated PSNR program)

计算时变的Hurst指数,包括主程序与子程序(Calculation time varying Hurst index, including the main program and subroutine)

非局部中值滤波 matlab代码,主要用于图像去噪，对于存在周期出现的图像有较好的效果，例如干涉图(Nonlocal median filter matlab code. It is mainly for image denoising and images with the existence of cycles are correspinding to good results, for example interferogram.)
