Abstract
The proof of the global and linear convergence of a fixed point iteration method for restoration, as well as an estimate for the rate of convergence have been discussed by many researchers. We present the global and linear convergence of a fixed point iteration method for a modified restoration problem. In addition, we show the equivalence among four different iterative methods: half-quadratic regularization, iteration based on the Bregman distance, inverse scale space method and generalized Weiszfeld’s method.
