WebHowever, alpha-expansion, a core step of graph cut, remains widely adopted as the optimization engine for later algorithms. Therefore, the goal of this project is to study the fundamentals of a class of graph cut algorithms and develop insights on how the algorithm handles occlusion, which remains a challenge in local methods. ...

WebThe α-expansion algorithm [3] involves global moves based on binary graph cut and typ- ically converges to low energy solutions in a few sweeps over label space. 2.1. Theα-expansion algorithm Since the ideas of iterative α-expansion play a cen- tral role in this paper we review it in more detail.
