Signature verification (SV) toolbox: Application of PSO-NN

Analysis of signature is a widely used and developed area of research for personal verification. A typical signature verification (SV) system generally consists of four components: data acquisition, preprocessing, feature extraction and verification. A reliable SV toolbox, based on the verification of off-line signatures is developed with the proposed algorithm. The technique is based on a neural network (NN) approach trained with particle swarm optimization (PSO) algorithm. To test the performance of the proposed PSO-NN algorithm two types of forgeries—unskilled and skilled—are examined. The experimental results are illustrated on the selected signature databases and presented herein. & 2009 Elsevier Ltd. All rights reserved.
