说明：  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 thresholding soft harr.rar file directory as the working directory. wavlet.fig then opened the boxes under the noise input noise intensity, In between 0-0.1 (not zero). Then point process button, it will indicate that the experimental results, including the original images, plus image noise, denoising image contrast and the current psnr value. Wavlet.m procedural documents.)
