Nonlinear Total-variation Denoising Model Based on AOS Method
MA Si-liang · Journal of Jilin University(Science Edition) · 2008
An addtive operator splitting(AOS) method is employed in the nonlinear total variation model(ROF model) for image denoising.The numerical discretization scheme is semi-implicit and unconditional stable.It overcomes the time step size restriction for explicit scheme.The method can easily be parallelized and one can gain an accelerated convergence.The experiments show that it is extremely promising compared to the explicit scheme.
