Abstract

My dissertation work investigates the use of qualitative spatial representations (QSR) about relative direction and distance for shape representation. This new approach -- which in contrast to previous approaches employs both direction and distance -- uniquely enables the generation of prototypical shapes from abstract representations. Using the conceptual neighborhood which is an established concept in QSR one can directly establish a conceptual neighborhood between shapes that translates into a similarity metric for shapes. Applying this similarity measure to a challenging computer vision problem yields promising first results.
