Graph cuts and alpha expansion
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. ... 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.

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 ...
