Interactive Image Segmentation with Graph-Cut in Python

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].

WebGraph cuts • In grouping, a weighted graph is split into disjoint sets (groups) where by some measure the similarity within a group is high and that across the group is low. • A graph-cut is a grouping technique in which the degree of dissimilarity between these two groups is computed as the total weight of edges removed between these 2 pieces.
