Wavelet image denoising has been well acknowledged as an important method of image denoising.Although it can preserve edge information,present methods ignore relativity of wavelet coefficients.According to the deficiency,a new image denoising method was proposed based on hidden markov tree.Experimental results showed that,compared with the usual denoising method,the proposed method could keep images edges from damaging and increase PSNR.
