Journal ArticleDOI
Bayesian and regularization methods for hyperparameter estimation in image restoration
TL;DR: This paper derives expressions for the iterative evaluation of the two hyperparameters applying the evidence and maximum a posteriori (MAP) analysis within the hierarchical Bayesian paradigm.
Journal ArticleDOI
Parameter Estimation in TV Image Restoration Using Variational Distribution Approximation
TL;DR: Experimental results show that the proposed approaches provide competitive performance without any assumptions about unknown hyperparameters and clearly outperform existing methods when additional information is included.
Book ChapterDOI
Bayesian blind deconvolution with general sparse image priors
TL;DR: A general method for blind image deconvolution using Bayesian inference with super-Gaussian sparse image priors is presented and theoretical and experimental results demonstrate that the proposed formulation is very effective, efficient, and flexible.
Book
Super Resolution of Images and Video
TL;DR: There is clear that there is a strong interplay between the tools and techniques developed for SR and a number of other inverse problems encountered in sig...
Journal ArticleDOI
Image restoration in astronomy: a Bayesian perspective
TL;DR: The Bayesian paradigm is described and the prior models used to restore astronomical images are examined, and important issues such as acceleration of algorithms, stopping rules, and parameter estimation are commented on.
