Introduction 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 ...

Methods for Learning Directed and Undirected Graphical Models Probabilistic graphical models provide a general framework for modeling relationships between multiple random variables. The main tool in ...

In conclusion, a two-species reaction–diffusion system on a directed graph can display a rich variety of instabilities, beyond the conventional scenario, which applies to symmetric (undirected ...
