New Polyhedral Study of Graph Multi-Separator Problem for Image Segmentation

By PulseAugur Editorial · [1 sources] ·

This paper introduces a polyhedral study of the graph multi-separator problem, proposed as an alternative to the lifted multicut problem for image segmentation. The authors characterize facets of the multi-separator polytope induced by integer linear programming inequalities and explore stronger inequalities. They also establish a totally dual integral description for paths and relate the multi-separator polytope to the boolean quadric polytope and the lifted multicut polytope. AI

IMPACT This research could lead to improved methods for image segmentation by offering a new approach to graph partitioning problems.

RANK_REASON The cluster contains a single academic paper detailing a new polyhedral study of a graph problem. [lever_c_demoted from research: ic=1 ai=0.4]
