WebApr 7, 2024 · Graph cuts是一种十分有用和流行的能量优化算法,在计算机视觉领域普遍应用于前背景分割(Image segmentation)、立体视觉(stereo vision)、抠图(Image matting)等。 WebCut (graph theory) In graph theory, a cut is a partition of the vertices of a graph into two disjoint subsets. [1] 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 ...
