In order to reduce alpha- expansion algorithm calculation, based on the label for alpha pixel to other pixel expansion process, first isolation than alpha between class relation, and only consider alpha class and the alpha relation between kind, so as to avoid alpha- expansion algorithm need to construct auxiliary node problem, reduce the s/t diagram of the number of edge, improve the computation efficiency of the algorithm. For relax the alpha class to the relationship between the constraints of alpha expansion, which makes the algorithm can be more easy to jump out of the energy function of the local minimum point and obtain better segmentation result.
