Comparison Between Method Emd And Wt Applied To Handwritten Signatures



Authors : Bouaziz Noureddine .

Abstract

We present an online approach for verifying handwritten signatures in this paper.The process of extracting parameters in this system involves applying Empirical Modal Decomposition, or EMD, to the unprocessed signals of an online signature.By utilizing the EMD's compression feature, only pertinent parameters are retained and combined using score fusion or concatenation.We compare the suggested system with prior research using WT (Wavelets Transform) parameters.Experiments conducted utilizing the Signature Verification Competition database (SVC2004) demonstrate the superiority of EMD parameters over WT parameters.
