Non-linear fourth-order telegraph-diffusion equation for noise removal

Abstract

Fourth-order partial differential equations (PDEs) for noise removal are able to provide a good trade-off between noise removal and edge preservation, and can avoid blocky effects often caused by second-order PDE. In this study, the authors propose a fourth-order telegraph-diffusion equation (TDE) for noise removal. In the authors method, a domain-based… (More)
