Data RangeT The following:Relate

Theorem 1: Maximum flow minimum cut quantification: In any network, the value of the maximum stream equals the minimum cut capacity Theorem 2: In any network, if F is a stream, cut (s,t) is a cut, and the value of F equals the capacity of cut

Image segmentation (3) from graph cut to grab cut Zouxy09@qq.com Http://blog.csdn.net/zouxy09 In the previous article, I learned about graphcut, but the grabcut we talked about is an iterative graph cut. The grabcut Algorithm in opencv is based on "grabcut"-Interactive foreground Extraction Using Iterated graph cuts is implemented in this article. This algorithm

[Email protected]Http://blog.csdn.net/zouxy09The previous article made an understanding of graphcut, and now we talk about the Grabcut is the improved version of it, is the iteration of graph Cut. The grabcut algorithm in OPENCV is implemented according to the article "Grabcut"-Interactive Foreground Extraction using iterated Graph Cuts. The algorithm takes advantage of the texture (color) information and the boundary (contrast) information in the ima

TEMPLATE 1 (main ):Property: the point with the same low [] value is the same connected component.Int RT, CNT;// RT records the root subscript. rt_son indicates the number of sons directly connected to the root. If it is greater than 1, the root is the cut point, which is easy to prove.Int vis [Max], dfn [Max], low [Max];// Dfn [I] indicates the depth of the I-th node in the Search Tree, and low [I] indicates the number of top node layers connected by

A graph of n points, for any four-point x,y,z,w, their minimum cut can not intersect. So we can divide and conquer to find the equivalent stream tree. The equivalent stream tree is such a tree, so that the minimum cut of the two points in the graph is the right of the tree corresponding to the minimum edge on the chain. It's not the same as the smallest cut tree.

Problem-solving report question Portal question: Give an undirected graph, as well as the start and end points. To delete some edges so that the start point and the end point are not connected, the number of edges to be deleted should be as few as possible when the sum of the right values of the deleted edges is the smallest. Obtain a ratio: the weight of the number of remaining edges and the number of deleted edges. Train of Thought: Obviously, a minimum cu
