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.
