Abstract:

Shape is an object property which has a big discrimination capacity. This is because the shape allows many numerical characterisations. Some of these numerical characterisations relate to the validation of certain intuitively clear shape properties (usually called shape descriptors) – e.g. shape convexity, shape elongation, shape compactness, etc. Methods for numerical validations, of such properties (i.e. shape descriptors) are called the shape measures. Some of shape descriptors have already assigned multiple shape measures (convexity, compactness, etc). Since shape descriptors have an intuitively clear meaning, the behaviour of the measures, assigned to them, can be predicted to some extent, which enables a priory estimate how a certain measure fits to the task performed.  The problems is that the number of shape descriptors is not large, comparing with the number of generic shape descriptors (usually do not have a clear geometric interpretation). In this talk, some ideas/results about how to overcome such a drawback and how to expand the applicability of shape/descriptors will be presented.
