高阶非局部变分模型

doi:10.3969/j.issn.1001-2400.2012.01.016

Abstract

Abstract:

To describe the nonlocal structure of images better and remove noise, this paper proposes a higher-order nonlocal variational model by defining a new weighted function. Theoretical analysis and numerical experiments are presented to demonstrate the performance of the proposed model, which is better than the original in terms of both PSNR and visual perception. As a result, the new model keeps the advantages of the nonlocal variational model, while it can preserve image features better.

Key words: nonlocal mean, variational model, denoising
