A Fractional Image Inpainting Model Using a Variant of Mumford-Shah Model

Abdul Halim, Abdur Rohim, B. V. Rathish Kumar +1

In this paper, we propose a fourth order PDE model for image inpainting based on a variant of the famous Mumford-Shah (MS) image segmentation model. Convexity splitting is used to…

Complete Flux Scheme for Elliptic Singularly Perturbed Differential-Difference Equations

Sunil Kumar, B. V. Rathish Kumar, J. H. M. Ten Thije Boonkkamp

In this study, we propose a new scheme named as complete flux scheme (CFS) based on the finite volume method for solving singularly perturbed differential-difference equations (SPD…
