摘要	To solve deblurring and denoising problem, we present a proof of the global and linear convergence of fixed point iteration, as well as an estimate for the rate of convergence is given. We show the equivalence among three different iterative methods: half-quadratic regularization, iteration based on Bergman distance, Weiszfeld's method. (c) 2006 Elsevier Inc. All rights reserved.
