Research of weighted dynamic timing warping in on-line handwritten signature
Huichuan Duan · Computer Engineering and Applications Journal · 2010
In this paper,a new method of on-line handwritten signature verification is presented.The normal pattern and local stability is obtained from reference patterns.Verification part adopts dynamic timing warping which shifts pressure as weighting.Through the matching distance of genuine signatures can calculate a set of thresholds.Distances which are less than the threshold are supposed to genuine signatures and the greater are forged ones.The method of this system can overcome the faults of normal dynamic timing warping using in on-line handwritten signature verification.Experiments also demonstrate that this new method has low computation and high performance,the FAR,FRR and EER also has obvious improvement.
