Abstract:

An assessment of the performance of various inversion algorithms is presented and compared with the Richardson-Lucy method, the currently favored approach used for the restoration of Hubble Space Telescope images. Numerical validations are made in the case of two simulated images.

Keywords: Ill-posed problem, ill-conditioned problem, regularization
