Abstract

We propose parametric geons as a volumetric description of object components for qualitative object recognition. Parametric geons are seven qualitative shape types defined by parameterized equations which control the size and degree of tapering and bending. The models provide global shape constraints which make model recovery procedures robust against noise and minor variations in object shape. The surface characteristics of parametric geons are discussed. The properties of parametric geons and conventional geon models are compared. Experiments fitting parametric geons to multiview data using stochastic optimization were performed. Results show that unique descriptions of single-part objects with minor shape variations can be obtained with the parametric geon models.
