为了取得更好的结果,采用一种基于Minimum s-t Cut三维表面重建算法。通过运用Delaunay三角化对3D点云空间进行自适应分解,利用可见性信息将表面重建问题转化为能量最小化问题,构建有向图,以Minimum s-t Cut方式求解能量最小化问题,得到最终表面重建模型。实验表明基于Minimum s-t Cut三维表面重建算法可以重建出较完整...
In section 3, we introduce the definitions of the size-constrained minimum s–t cut problems. We give a polynomial time algorithm for solving the minimum s–t cut with at least k vertices problem when k is bounded by a constant. In section 4, we prove that these size-constrained minimum...
minimum_cut_value(flowG, _s, _t, capacity='capacity', flow_func=None, **kwargs) 计算最小值 (s, t)-cut 的值。 使用max-flowmin-cut定理,即最小容量切割的容量等于最大流量的流量值。 参数: flowG:NetworkX 图 图表的边应该有一个名为‘capacity’ 的属性。如果此属性不存在,则认为边具有无限...

本文简要介绍 networkx.algorithms.connectivity.cuts.minimum_st_edge_cut 的用法。 用法: minimum_st_edge_cut(G, s, t, flow_func=None, auxiliary=None, residual=None) 返回最小 (s, t) 割的cut-set 的边。 此函数返回最小基数的边集,如果删除,将破坏 G 中源和目标之间的所有路径。不考虑边权重。
Consider a network G=(V,E) with source s and sink t. An s-t cut is a partition of nodes set V into two parts such that s and t belong to different parts. The cut set is the subset of E with all edges connecting nodes in different parts. A minimum cut is the one whose cut ...

An s{\operatorname{-}}t s{\operatorname{-}}t minimum cut in a graph corresponds to a minimum weight subset of edges whose removal disconnects vertices s s and t t . Finding such a cut is a classic problem that is dual to that of finding a maximum flow from s s to t t . In...
