dc.description.abstract | 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 transformed into an equivalent constrainedminimization problem by tearing-andinterconnecting domain decomposition. Then, the continuity constraints on the subdomain interfaces are treated by introducing Lagrange multipliers. The resulting saddle point problem is solved by the first order primal-dual algorithm. We apply the proposed method to image denoising, inpainting, and segmentation problems with either L2-fidelity or L1-fidelity. Numerical results show that the proposed method outperforms the existing state-of-the-art methods. | - |
