Abstract

A new framework is presented that uses tools from duality theory of linear programming to derive graph-cut based combinatorial algorithms for approximating NP-hard classification problems. The derived algorithms include 驴-expansion graph cut techniques merely as a special case, have guaranteed optimality properties even in cases where á-expansion techniques fail to do so and can provide very tight per-instance suboptimality bounds in all occasions.
