متن کاملCorner cuts are close to optimal: From solid grids to polygons and back
We study the solution quality for min-cut problems on graphs when restricting the shapes of the allowed cuts. In particular we are interested in min-cut problems with additional size constraints on the parts being cut out from the graph. Such problems include the bisection problem, separator problem, or the sparsest cut problem. We therefore aim at cutting out a given number m of vertices from ...

This paper introduces an operator for the detection of the true location and orientation of corners. Its strength in dealing with junctions as well as corners is demonstrated. With this method, corner points are detected as intensity patterns that are anisotropic along several directions. Pixels belonging to the arms of the detected corners are analysed, and a histogram search provides a measur...
