Abstract
This paper deals with the definition of abstraction tools for deriving high-level descriptions of complex shape models. Among the wide range of shape descriptors, topological graph-like representations provide a powerful and synthetic sketch of the object, and also capture its inner structure, that is how features connect together to give the overall shape. This aspect makes them useful to describe complex 3D objects in various applications as modelling, morphing, matching and recognition. The approach therein presented deals with the extraction of protrusion-like features of the input object based on a multi-scale curvature evaluation of its surface; then, a skeleton is constructed by taking the tips of the protrusions as seed points for expanding topological rings on it.
