Regularization and Smoothing for the Restoration of Hubble Space Telescope Images

P. Benvenuti F. Maggio S. Seatzu


Two numerical methods for the restoration of noisy images from the Hubble Space Telescope are presented. The first one stems from a B-spline expansion followed by the Tikhonov regularization method. The second one is based on a coarse smoothing coupled with the Tikhonov regularization. The effectiveness of these methods is illustrated by the restoration of some images already proposed in the literature.
