Abdelgader Siddig, Samah A. F. Manssor · 2019
Computing time is an important issue in computational mathematics and computer vision. In this work, fast explicit diffusion (FED) scheme is used to solve a fourth-order nonlinear partial differential equation for noise removal. The numerical results illustrate the effective of the scheme over the traditional methods. Our results have been compared with three popular fourth-order models, You and Kaveh (YK) model, Lysaker, Lundervold and Tai (LLT) model and the mean curvature (MC) model. The proposed strategy has the prevalence in terms of removing noise whereas protecting image features with less computing time.
