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 cost of a corresponding cut of the graph. The max-ﬂow algorithm is used to ﬁnd the minimum cut of the graph, which corresponds to a minimum conﬁguration x! of E(x). The max-ﬂow algorithm requires a graph with non-negative edge weights, which means all quadratic terms must be submodular [10]: E ij(0,0)+E ij(1,1) ≤ E ij(0,1)+E ij(1 ... dewars bottle price dewars bottle sizes
