Research on the Computer-aided Quantity Analysis of Pen Pressure in Signatures
Objective To analyze pen pressure characteristics fast and accurately in signature examination,and realize correlation examination between signatures on paper and digital signatures.Methods A static signature pen pressure characteristic analysis system was developed,which enables the visualization analysis of pen pressure in signatures on paper.Moreover,a dynamic signature pen pressure characteristic analysis system was developed for the quantitative analysis of pen pressure in digital signatures.Results The two systems allowed the examiners to perform visualization analysis of pen pressure in black gel pen signatures and quantitative examination of pen pressure in digital signatures.A related examination of pen pressure in both types of signatures was achieved,improving the accuracy of signature identification.Conclusion The static and dynamic signature pen pressure characteristic analysis system can assist in the quantitative analysis of pen pressure in signatures.
