Graph cuts
WebGraph Cut [Boykov and Jolly 2001; Greig et al. 1989] is a pow-erful optimisation technique that can be used in a setting similar to Bayes Matting, including trimaps and probabilistic colour mod-els, to achieve robust segmentation even in camouage, when fore-ground and background colour distributions are not well separated. WebRecently, an approach based on optimization by graph-cut has been developed which successfully combines both types of information. In this paper we extend the graph-cut approach in three respects. First, we …

WebIn graph theory, a minimum cut or min-cut of a graph is a cut (a partition of the vertices of a graph into two disjoint subsets) that is minimal in some metric. Variations of the minimum cut problem consider weighted graphs, directed graphs, terminals, and partitioning the vertices into more than two sets.

WebGraph-Cuts for F-Formation (GCFF). Presented by Setti et al. [4], it proposes an iterative approach that starts by assuming an arbitrarily high number of F-formations: after that, a hill-climbing optimization alternates between assigning individuals to groups using a graph-cut based optimization, and updating the centers of the F-formations ...
