Abstract

In any image post-processing system, an imperfect knowledge of the system point-spread function (PSF) leads to errors in the estimation of the truth image from the image data. Here we treat the problem of PSF uncertainty resulting from either uncorrected or partially corrected atmospheric turbulence related phase errors and its impact on image estimation in the presence of Poisson count statistics.
