This paper presents a graph cut approach to the image segmentation task. Considering the image to be a directed graph with two nodes representing the source (object) and the sink (background), the ...

We show how certain basic results about cycles in directed and undirected graphs can be used to solve some clever problems that appeared in major mathematics competitions. Journal Information ...
