Leveling the Grid 2013-12-18 eng Karrenbauer, Andreas deposit-license 2012-05-09T09:12:52Z Motivated by an application in image processing, we introduce the grid-leveling problem. It turns out to be the dual of a minimum cost ow problem for an apex graph with a grid graph as its basis. We present an O(n3=2) algorithm for this problem. The optimum solution recovers missing DC coe cients from image and video coding by Discrete Cosine Transform used in popular standards like JPEG and MPEG. Generally, we prove that there is an O(n3=2) min-cost ow algorithm for networks that, after removing one node, are planar, have bounded degrees, and have bounded capacities. The costs may be arbitrary.
