一种基于小波变换的图像消噪算法

An Image Denoising Method Based on Wavelet Transform

该文在自适应树小波萎缩法的基础上,结合小波系数的零树编码思想和小波变换的信噪分离特性给出了一种新的小波消噪算法。该算法不仅减少了运算量,而且在消噪和保留奇异点信息方面也取得了较好的效果。

In this paper, a new method of image denoising is presented ,which is built upon the ideas of Embedded Zerotree Wavelet （EZW） encoder and separate character of signals and noises. This method is not only less than Tree-Adapted Wavelet Shrinkage （TAWS） method in operation amounts but also excellent in image denoising results and reservation of singularity information.
