Voronoi Diagrams for Moving Disks and Applications
In this paper we discuss the kinetic maintenance of the Euclidean Voronoi diagram and its dual, the Delaunay triangulation, for a set of moving disks. The most important aspect in ...

Memory efficient skeletonization of utility maps
An algorithm is presented that allows to perform skeletonization of large maps with much lower memory requirements than with the straightforward approach. The maps are divided int...
