In this paper, we present a novel methodology for the classification of static handwritten signatures. We extract features from each user’s high-pressure points by filtering the skeletonized-binarized digital signatures at seven different thresholds. We compare the sequences obtained using the Dynamic Time Warping (DTW) algorithm with five metrics...
