"""
Here, we train a generative adversarial network (GAN) on a sample of 4550 images of nearby galaxies at 0.01 < z < 0.02 from the Sloan Digital Sky Survey [...] can recover features from artificially degraded images with worse seeing and higher noise than the original with a performance that far exceeds simple deconvolution.
[...]
Deconvolution has long been known as an ‘ill-posed’ inverse problem because there is often no unique solution if one follows the signal processing approach of backwards modelling [...] if the algorithm knows what a galaxy should look like or it knows the output needs to have certain properties such as being ‘sharp’, it will make more informative decisions when choosing among all possible solutions.
