Wavelet shrinkage with correlated wavelet coefficients
This paper investigates the statistical characterizationof multiscale wavelet coefficients corresponding to random signals and images. Virtually all approaches to wavelet shrinkag...

Bayesian sigmoid shrinkage with improper variance priors and an application to wavelet denoising
The normal Bayesian linear model is extended by assigning a flat prior to the th power of the variance components of the regression coefficients (0<

salienShrink: Saliency-Based Wavelet Shrinkage
This paper describes salienShrink, a method to denoise images based on computing a map of salient coefficients in the wavelet domain and use it to improve common denoising algorit...

Multicomponent Image Restoration, an Experimental Study
Abstract. In this paper, we study the problem of restoring multicomponent images. In particular, we investigate the effects of accounting for the correlation between the image com...

A Wavelet-Based Image Denoising Technique Using Spatial Priors
We propose a new wavelet-based method for im age denoising that applies the Bayesian framework, using prior knowledge about the spatial clustering of the wavelet coefficients. Loc...
