Abstract

Abstract: A time dependent model for deblurring and denoising problems is proposed.Comparisons with the Rudin-Osher-Fatemi model are made in numerical experiments with antireflective boundary conditions and medium boundary conditions.The results demonstrate that the error with medium boundary conditions is smaller than that with antireflective boundary conditions.

Key words: deblurring, denoising, antireflective boundary conditions, medium boundary conditions
