Abstract :
The nonlinear diffusion PDE have been broadly applied in image processing. In this paper we propose a convection - diffusion filter by adding a convection term in the modified diffusion equation as a physical interpretation for removing the noise. We study the dynamics of such equations by the discretization of this convection - diffusion model via Cellular Nonlinear Networks (CNN). Numerical experiments show that our method is reasonably better in removing noise.
