A Novel Variational PDE Technique for Image Denoising

摘要

A robust variational PDE model for image noise removal is proposed in this paper. One considers an energy functional to be minimized, based on a novel smoothing constraint. Then, the corresponding Euler-Lagrange equation is determined. The obtained PDE model is solved, by using a numerical discretization scheme. Some results of our image denoising experiments and method comparisons are also described in this article.
