Abstract 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.
