Kinematic Reconstruction of Calligraphic Traces from Shape Features

Our goal is to be able to reproduce computationally calligraphic traces, e.g. as found in the art practices of graffiti and various forms of more traditional calligraphy, while mimicking the production process of such art forms. We design our user interfaces in a procedural generation and computer aided design (CAD) setting. As a result, we seek to seamlessly work between data used in design packages (without kinematics) and data easily digitised by users (e.g. online, with kinematics). To achieve these goals, we propose a method that allows to reconstruct kinematics from solely the geometric trace of handwritten trace in the form of parameters of the Sigma-Lognormal model. We purposely ignore the kinematics possibly embedded in the data in order to treat online data and vector patterns with the same procedure.
