A weighted denoising method based on Bregman iterative regularization and gradient projection algorithms

摘要

A weighted Bregman-Gradient Projection denoising method, based on the Bregman iterative regularization (BIR) method and Chambolle’s Gradient Projection method (or dual denoising method) is established. Some applications to image denoising on a 1-dimensional curve, 2-dimensional gray image and 3-dimensional color image are presented.Compared with the main results of the literatures, the present numerical results of the proposed method are improved.
