"Confocal Ellipse-based Distance and Confocal Elliptical Field for Polygonal Shapes.";

in: "IAPR/ICPR 2018 International Conference on Pattern Recognition", IEEE Catalog Number: CFP18182-USB; IEEE Computer Society, 2018, ISBN: 978-1-5386-3787-6, 3025 - 3030.

The paper introduces a novel confocal ellipse-based distance (CED), that is based on the properties of the confocal ellipses. This distance is used to produce a confocal elliptical field (CEF). The Euclidean Distance Transform (EDT) of a single point (called seed) generates a distance field of concentric circles. The sum of two such distance fields of two distinct seed points produces a distance field of confocal ellipses. This fact enables to adapt CED and CEF to the discrete case, referred to as CEDDT and CEF-DT. The properties of the CEF and CEF-DT make them useful for skeletonization, in particular for efficient removal of the spurious branches.
