Fast Approximate Energy Minimization via Graph Cuts

Webrithms based on graph cuts that eﬃciently ﬁnd a local minimum with respect to two types of large moves, namely expansion moves and swap moves. These moves can si-multaneously change the labels of arbitrarily large sets of pixels. In contrast, many standard algorithms (including simulated annealing) use small moves where only one Webelementary cuts C on G and labellings that are one within one α- expansion of f. And the cost of a cut C on G is C = E( fC ). Proof :-– The label f p C at the pixel p determines …

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 ...
