Graph cut opencv
WebThe graphcut algorithm is the generic min-cut algorithm from graph theory, on a specific type of graph: Each pixel is a node, and is connected to it's 4 or 8 surrounding neighbors. There is a virtual "source" node denoting foreground, and a virtual "sink" node denoting background. The source and sink nodes are both connected to every single ... WebAbout.

WebAug 1, 2004 · In this paper we extend the graph-cut approach in three respects. First, we have developed a more powerful, iterative version of the optimisation. Secondly, the power of the iterative algorithm is used to simplify substantially the user interaction needed for a given quality of result. Thirdly, a robust algorithm for "border matting" has been ... WebGraphCut分割实例. Contribute to cm-jsw/GraphCut development by creating an account on GitHub.
WebOct 9, 2014 · I have to define a new graph from an image with custom weight of arcs and then use graph cut to find the min cut. I know that there is the grabcut opencv function that uses a user-specified bounding box around the object to be segmented to find the background/foreground.
