Splitting the skeleton into simple arcs and curves via iterated removal of peripheral subsets

Abstract

The skeleton of a tridimensional object is split into a number of components, either simple arcs or simple curves, by means of an iterated removal of peripheral skeleton subsets. Each component is vectorised ana characterised by a number of quantitative features related to geometrical properties of the region of the object mapped into the skeleton component. An ordering of the components is done, based on the iteration at which components are detected as peripheral. The proposed skeleton decomposition can be suitably employed in a recognition task
