An adaptive Bayesian estimator for image denoising in shearlet domain is presented, where bivariate probability densities are used as the prior model of shearlet coefficients of images. The bivariate probability density function is proposed to model the statistical dependence between a coefficient and its parent and it is shown to fit very well to the observed noise-free histograms. Under this prior,...
An adaptive Bayesian estimator for image denoising in shearlet domain is presented, where the Bessel K Form (BKF) densities are used as the prior model of shearlet coefficients of images. The BKF densities are shown to fit very well to the observed noise-free histograms. Under this prior, a Bayesian sheartlet estimator is derived by using the minimum mean square error (MMSE) rule. Finally, a simulation...
