Information Dynamics in Image Deconvolution
Abstract
This report consists of somewhat abridged versions of all previously submitted progress reports, placed here in individual sections, followed by a section on the progress made in the last 12-month performance period and on the promising future directions for our work. A broad understanding of all aspects of image formation, detection, and processing in information theoretic terms has been achieved in our studies under direct support of the Contract. Specifically, we have: (1) shown how prior knowledge about the object being imaged, particularly about the support of its intensity distribution, can be regarded as a gain of information; (2) computed the theoretical limit on information throughput, i.e., the channel capacity of an astronomical imaging system; (3) computed theoretically and in simulation the detailed characteristics of the dynamics of noise versus information in imaging under turbulence when support information is employed as a post processing tool; and (4) gained a preliminary understanding of the inverse relation between noise and information.
