Vector total fractional-order variation and its applications for color image denoising and decomposition

摘要

In this paper, a vector total fractional-order variation (VTV-beta) is proposed. Then, VTV-beta model and G(beta)(Omega) model are proposed for color image denoising and decomposition, respectively. Some properties of the VTV-beta are investigated and an alternative algorithm is used to solve the two models. Some experimental results are given to show the effectiveness and advantages of our methods. (C) 2019 Elsevier Inc. All rights reserved.
