Total variation image restoration: numerical methods and extensions
Peter A. Blomgren, Tony Fan-Cheong Chan, Pep Mulet, Chee Kit Wong · 2002
We describe some numerical techniques for the total variation image restoration method, namely a primal-dual linearization for the Euler-Lagrange equations and some preconditioning issues. We also highlight extension of this technique to color images, blind deconvolution and the staircasing effect.
