Web如图1所示，点分割是将图的结点分配到各个子图中，维持结点之间子图的完整性，这个时候可能造成某些结点之间的边被切掉(edge-cut)；同理边分割是将图的边分配到各个子图中，每组分配的边构成子图，这个时候造成某 … WebMay 5, 2024 · Graph Cut[1]算法是一种直接基于图切算法的图像分割技术。它仅需要在前景和背景处各画几笔作为输入，算法将建立各个像素点与前景背景相似度的赋权图，并通过求解最小切割区分前景和背景。

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 … See more A cut C = (S,T) is a partition of V of a graph G = (V,E) into two subsets S and T. The cut-set of a cut C = (S,T) is the set {(u,v) ∈ E u ∈ S, v ∈ T} of edges that have one endpoint in S and the other endpoint in T. If s … See more A cut is maximum if the size of the cut is not smaller than the size of any other cut. The illustration on the right shows a maximum cut: the size of the cut is equal to 5, and there is no cut of size 6, or E (the number of edges), because the graph is not See more The family of all cut sets of an undirected graph is known as the cut space of the graph.
