In this paper, we propose a novel approach to explore image denoising for patch based image process.The importance measurement model of Rough Entropy and the importance reduction method of wavelet coefficients are given.This paper combines the rough set theory with the denoising method of wavelet threshold, regarding the high-frequency information blocks in the transform domain as similar ones, and adopting importance Reduction Methods to contract the coefficients.The simulation results show that this method is effective.
