传统图像去噪方法对图像的细节破坏比较严重，利用小波可以将纹理细节和噪声在高频部分以不同特性加以区分，从而在保存图像纹理细节的同时去除噪声。-The traditional image denoising method is more serious damage on the details of the image using wavelet texture detail and noise in the high frequency part of the different characteristics distinguish remove noise, and thus save the image texture detail.
