Abstract:

In this paper, the authors propose a new model for image restoration problems, based on the total variation minimizing models proposed by Rudin, Osher, and Fatemi(ROF). Since the functional is nonquadratic, the dual method and Newton's method are used to compute the regularized solutions.The numerical experiments show the improvement is fairly valid.

Key words: Image restoration, Total variation, Dual method, Euler equation
