With the “smoothness” slider we can adjust the smoothness of the segmentation to avoid some small extrema to corrupt our segmentation. In our example, we found that a value of about 600 gives reasonable results. The outcome of the plugin is a binary image, with ...

Interactive Image Segmentation with Graph-Cut in Python

As applied in the field of computer vision, graph cut optimization can be employed to efficiently solve a wide variety of low-level computer vision problems (early vision ), such as image smoothing, the stereo correspondence problem, image segmentation, object co-segmentation, and many other computer vision problems that can be formulated in terms of energy minimization. Many of these energy minimization problems can be approximated by solving a maximum flow problem in a graph (and … WebWhat is a “cut”? A graph G = (V,E) can be partitioned into two disjoint sets, by simply removing edges connecting the two parts. The degree of dissimilarity between these two pieces can be computed as total weight of the edges that have been removed. In graph theoretic language it is called the cut: [2].

"WebCut ( graph theory) In graph theory, a cut is a partition of the vertices of a graph into two disjoint subsets. The cut-set of the cut is the set of edges whose end points are in different subsets of the partition. Edges are said to be crossing the cut if they are in its cut - set. " - Graph cut wikipedia

WebConstructing the covering graph. The transitive reduction or covering graph of the Dedekind–MacNeille completion describes the order relation between its elements in a concise way: each neighbor of a cut must remove an element of the original partial order from either the upper or lower set of the cut, so each vertex has at most n neighbors.
