Abstract

The multi-frame blind deconvolution algorithm is considered for processing astronomical speckle images when only a few frames of data are collected. It has been noted that when the speckle data contains even moderate amounts of shot noise the algorithm often converges to the trivial point solution. In this paper we consider a `penalized' blind deconvolution algorithm in which the penalty function is based on the Knox-Thompson algorithm.
