Graph cuts and alpha expansion
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 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.
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. 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 …
