Abstract
In this paper we propose and compare the use of two iterative solvers using the Crank-Nicolson finite difference method, for image denoising via Partial differential equations (PDE) models such as Bilateral-filter-based model. The solvers considered here are: Successive-over-Relaxation (SOR) and an advanced solver known as Hybrid Bi-Conjugate Gradient Stabilized (Hybrid BiCGStab) method. We demonstrate that proposed hybrid BiCGStab solver for denoising yields better performance in terms of MSSIM and PSNR, and is more efficient than existing SOR solver and a state-of-the-art approach.
