Abstract :
This paper proposes a method that comes from the minimum cut problem in network flow theory to minimize the MRF energy of posteriori probability. Then maximum flow or minimum cut algorithm is used to deal with MRF segmentation. Experiments on SAR images prove that the proposed method has better accuracy and faster efficiency than standard algorithms.
