Abstract This article introduces a fast meshless algorithm for the numerical solution nonlinear partial differential equations
(PDE) by Radial Basis Functions (RBFs) approximation connected with the Total Variation (TV)-based minimization functional and to show its application to image denoising containing multiplicative noise. These capabilities
used within the proposed algorithm have not only the quality of image denoising, edge preservation but also the
property of minimization of staircase effect which results in blocky effects in the images. It is worth mentioning
that the recommended method can be easily employed for nonlinear problems due to the lack of dependence on a
mesh or… More >
