A Nonlinear Parabolic Partial Differential Equation Model for Image Enhancement

Authors: Tudor Barbu


We present a robust nonlinear parabolic partial differential equation (PDE)-based denoising scheme in this article. Our approach is based on a second-order anisotropic diffusion model that is described first. Then, a consistent and explicit numerical approximation algorithm is constructed for this continuous model by using the finite-difference method. Finally, our restoration experiments and method comparison, which prove the effectiveness of this proposed technique, are discussed in this paper.

Keywords: anisotropic diffusion, image denoising and restoration, nonlinear PDE model, numerical approximation scheme, finite differences
