Considering the shortcomings of Wavelet and Contourlet when applied to image denoising,we proposed a new method based on Shearlet transform and Bayesian MAP estimation. Firstly,the source images were decomposed into several subbands using Shearlet. Then,Bayesian MAP estimation was adopted to estimate these multi-direction subbands. Finally,the denoised image was obtained by performing the inverse Shearlet transform on the coefficients. The experimental results show that: Compared with other denoising method...
