Checking the literature about image segmentation, if I am not wrong, there are two main approaches:

  • Variational approach e.g. level-set optimization in Chan-Vese
  • Combinatorial approach e.g. using graph cut in GrabCut

Can someone give me some high-level comparison between these two directions?

For example, I feel with level-set optimization one can easily incorporate image structure (e.g. edges) into the energy function, which is not easy in Grabcut. Am I correct?

Thanks.

Level set is for continuous segmentation, multiphase. But Graph cut is for discrete segmentation, only two phase
