The Restoration of Astronomical Images
This lecture presents practical applications of pixon-based Bayesian estimation to the restoration of astronomical images. It discusses the e®ects of noise, e®ects of ̄nite sampling on resolution, and special problems associated with spatially correlated noise introduced by mosaicing. Comparisons to other methods demonstrate the signi ̄cant improvements a®orded by pixonbased methods and illustrat...
متن کاملAn iterative mixed1 norm image restoration algorithm
In this paper; we propose an iterative mired norm image restoration algorithm. A functional which combines the least mean squares (LMS) and the least mean fourth (LMF) functionals is proposed. A function of the kurtosis: is used to determine the relative importance between the L A 8 and the LMF functionals. An iterative algorithm is utilized for obtaining a solution and its convergence is analy...
متن کاملIterative adaptive lp restoration of blurred images
A new model adaptive method is presented for restoration of blurred and noise corrupted images by exploiting information available from observed data to choose the apprcpriate optimization criterion. The derived maximum likelihood solution is based on the 1 , minimization criterion that naturally arises from the adoption of the generalized p-Gaussian family of probability distributions as an ad...

متن کاملProbabilistic Model-Based Restoration of Short-Exposure Astronomical Images
We present a novel multiimage restoration method based on the underlying spatial probabilistic image model for astronomical image restoration if degradation obeys a linear degradation model with the unknown possibly nonhomogeneous point-spread function. The method assumes that for every ideal undegraded unobservable image several degraded observed images are available. Pixels in the vicinity of...
