‘The Equator–Pole grid system’: an overset grid system for the sphere, with an optimal uniformity property

Tellus: Series A, Dynamic Meteorology and Oceanography, 2018
This article proposes a new grid system for the sphere, which consists of three orthogonal and almost uniform grids. The basic one is a latitude-longitude grid covering an annular band around the equator.

Analysis of iterative methods for solving a Ginzburg-Landau equation

, 2005
. Very recently we have proposed to use a complex Ginzburg-Landau equation for high contrast inpainting, to restore higher dimensional (volumetric) data (which has applications in frame interpolation), improving sparsely sampled data and to fill in ...

High Order Parallel Iterative Method for Diffusion Equations

, 2009
In this paper, we consider the initial boundary value problems of 1D diffusion equations. Based on a high order absolutely stable implicit scheme, we first construct two saul'yev asymmetry iterative schemes, and then present a class of parallel ...

Numerical modeling for the recovery of fine structures in PDE-based image denoising,” (submitted to Image and Vision Computing

, 2008
PDE-based image denoising processes often lead to significant loss of fine structures such as edges and textures. This article is concerned with numerical modeling for PDE-based denoising models that can preserve/recover fine structures in the restored ...
