Abstract: In this paper we introduce a second order differential\noperator in order to partition discrete objects into meaningful\nparts. One of these parts contains all points of\nthe object’s medial axis which is a widely used shape\ndescriptor.\nSince aliasing is a fundamental problem for methods\nbased on the boundary of discrete objects we use a bilateral\nfilter to reduce the artefacts significantly.\nAs a result of the partitioning and filtering we obtain\na lattice point set (a superset of the medial axis) which\nis robust against noise and aliasing and which is rotationally\ninvariant. The lattice point set can be used for\ninstance to compute the medial axis or similar shape\ndescriptors.
