ABSTRACT

In this paper, we describe the use of differential profiles, which are computed from 2D shapes smoothed with Gaussian functions, as the shape features for building a shape retrieval system. We build a global shape component dictionary from all the shape descriptors collected from shapes available in a database and then represent each shape as a probabilistic mixture of elements from such a dictionary. Finally, shape retrieval from a given database is simply done by comparing the mixing coefficients of the model of a query shape and those of known shapes. Our retrieval experiments are done on both object contour and line drawing collections and show promising results.
