Fast Nonoverlapping Block Jacobi Method for the Dual Rudin--Osher--Fatemi Model
Chang-Ock Lee, Jongho Park
We consider nonoverlapping domain decomposition methods for the Rudin--Osher--Fatemi~(ROF) model, which is one of the standard models in mathematical image processing. The image do…

A Finite Element Nonoverlapping Domain Decomposition Method with Lagrange Multipliers for the Dual Total Variation Minimizations
Chang-Ock Lee, Jongho Park
In this paper, we consider a primal-dual domain decomposition method for total variation regularized problems appearing in mathematical image processing. The model problem is trans…
