A convergent blind deconvolution method for post-adaptive-optics astronomical imaging
M. Prato, A. La Camera, S. Bonettini +1
In this paper we propose a blind deconvolution method which applies to data perturbed by Poisson noise. The objective function is a generalized Kullback-Leibler divergence, dependi…
