Graph Cut - an overview ScienceDirect Topics

Websegmentation approaches based on graph cuts. The common theme underlying these approaches is the formation of a weighted graph, where each vertex corresponds to an image pixel or a region. The weight of each edge connecting two pixels or two regions represents the likelihood that they belong to the same segment. A graph is Webmore recent formulations in terms of graph cuts (e.g., [14, 18]) and spectral methods (e.g., [16]). Graph-based image segmentation techniques generally represent the problem in terms of a graph G = (V;E) where each node vi 2 V corresponds to a pixel in the image, and the edges in E connect certain pairs of neighboring pixels.
