Wavelet-based image denoising algorithms are of great interest in the study of image denoising.But most of the researches have focused on only one set of observations.Based on study of the algorithm proposed by S.Chang which recovers an image from it's multiple noisy copies by two-band wavelet transform,the authors extend it to M-band wavelet transform,and propose a multiple image copies denoising algorithm based on M-band wavelet transform.The experimental results show that the denoising performance is better than the two-band wavelet under the same condition.
