According to a recent mathematical theory the intuitive concept of shape can be formalized through functions, named "size functions", which convey information on both the topological and metric properties of the viewed shape. In this paper the main concepts and results of the theory are first reviewed in a somewhat intuitive fashion. Then, an algorithm for the computation of discrete size functions is presented. Finally, by introducing a suitable distance function, it is shown that size functions can be successfully used for both shape description and recognition from real images.
