Webdeveloped based on graph cuts [6,7,12,14,21]. These methods are fast enough to be practical, and yield quite promising experimental results for stereo [22, 27]. Unlike simulated annealing, graph cut methods cannot be applied to an arbitrary energy function; instead, for each energy function to be minimized, a careful graph construction must be ... 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.

The cost of each edge is reﬂected by the edge’s thickness. Minimum cost cut is at-tracted to cheap edges. 2.3. Graph cut methods in vision ipheion dialystemonIn graph theory, a cut is a partition of the vertices of a graph into two disjoint subsets. Any cut determines a cut-set, the set of edges that have one endpoint in each subset of the partition. These edges are said to cross the cut. In a connected graph, each cut-set determines a unique cut, and in some cases cuts are identified with their cut-sets rather than with their vertex partitions.
