function PSNR2 = psnr(I,I_iter) 计算峰值信噪比 I : 原始信号 I_iter : 加噪信号(function PSNR2 = psnr (I, I_iter) calculate the peak signal to noise ratio I: the original signal I_iter: adding noise signal)

说明：  里面有一篇非局部均值去噪的文章，并附有代码。经调试，代码正确。(There are a non-local means denoising article, along with the code. After debugging, the code is correct.)

说明：  利用小波方法对语音信号进行去噪，取得了很好的效果。(using wavelet method of voice signal denoising, and achieved very good results.)
