An interactive trajectory synthesizer to study outlier patterns in handwriting recognition and signature verification

Abstract

A software tool has been developed to simulate complex pen tip trajectories and their corresponding velocity profiles based on the kinematic theory of rapid human movements and its lognormal model. The set of equations used to generate the various signals is shortly introduced. The application interface and the functionalities of the main modules are schematized and described. Finally typical simulations results are presented in the context of an interactive comparative analysis of on-line signature data
