Graph cuts python

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. WebIt cuts the graph into two separating source node and sink node with minimum cost function. The cost function is the sum of all weights of the edges that are cut. After the cut, all the pixels connected to source node become foreground and those connected to sink node become background.
