Description: 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.

Description: 常规小波阈值去噪方法是在假定小波系数独立的条件下进行处理的,没有考虑到小
波系数在相邻尺度上的相关性.因此,也同样受到去噪和保留有用高频信息两难的困扰-Conventional wavelet thresholding denoising method is the assumption that the wavelet coefficients under the conditions of an independent deal with, and does not take into account the wavelet coefficients in adjacent scales of relevance. Therefore, it will also be useful by the de-noising and retain high-frequency information dilemma problems Platform: |
