鲁棒的阿尔法扩展Pn势场实现，c/c++，很经典，找了很久。-This software library implements the alpha expansion for robust P^N potentials described in P. Kohli, L. Ladicky, and P. Torr. Graph cuts for minimizing robust higher order potentials. Technical report, Oxford Br

针对摸个引用，能够分离有限元模型的表面。-It can be useful to separate the surface of a finite element model for certain applications such as fatigue analysis. For example, if cracks are known to initiate on the material surface, then the inclusion of sub-surface element
