说明：  小波软阈值去噪soft harr.rar 小波软阈值去噪soft harr.rar 将文件所在目录设为工作目录，然后打开wavlet.fig,在noise提示框下输入噪声强度，在0-0.1之间（不能为零）。然后点process按钮，就会显示实验结果，包括原图像，加噪图像，去噪图像的对比以及当前的psnr值。 wavlet.m是程序文件
(Wavelet soft-threshold denoising soft harr.rar wavelet soft-threshold denoising soft harr.rar document directory Set working directory is located, and then open the wavlet.fig, prompt box in the noise input noise strength, in between 0-0.1 (Can not zero). Button and then point process, it will show the experimental results, including the original image, noise image denoising image contrast as well as the current value of the PSNR. wavlet.m is a program file)
