Size functions for signature recognition
Pietro Donatini, Patrizio Frosini, Alberto Lovato · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1998
Size functions are a mathematical tool for comparing shapes represented as topological spaces. In this paper we introduce a method for describing a set of size functions corresponding to a given class of objects. An example of the application of this method for signature recognition is presented.
