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 ... WebTo use alpha-expansions for decoding, we can use: alphaExpDecode = UGM_Decode_AlphaExpansion(nodePot,edgePot,edgeStruct,@UGM_Decode_GraphCut); Alpha-Expansion Beta-Shrink Moves Alpha-expansion moves often lead to better performance than alpha-beta swap moves.

WebThis new move-making scheme is used to efficiently infer per-pixel 3D plane labels on a pairwise Markov random field (MRF) that effectively combines recently proposed slanted patch matching and curvature regularization terms. The local expansion moves are presented as many alpha-expansions defined for small grid regions.
