DOMAIN DECOMPOSITION METHODS WITH GRAPH CUTS ALGORITHMS FOR IMAGE SEGMENTATION XUE-CHENG TAI∗ AND YUPING DUAN† Abstract. Recently, it is shown that graph cuts algorithms can be used to solve some variational image restoration problems, especially connected with noise removal and segmentation. For very large size problems, the cost for memory and computation increase dramatically. We propose a domain decomposition method with graph cuts algorithms. We show that the new approach is cost effective both for memory and computation. Experiments with large size 2D and 3D data are supplied to show the efficiency of the algorithms. Key words. multiphase Mumford-Shah, graph cuts, image segmentation, domain decomposition 1. Introduction. Segmentation is one of the fundamental tasks for image processing.
