Graph cuts and alpha expansion

WebOct 7, 2012 · Expansion algorithm is a popular optimization method for labeling problems. For many common energies, each expansion step can be optimally solved with a min-cut/max flow algorithm. While the... 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.
