Ninth International Conference on Document Analysis and Recognition (ICDAR 2007) Vol 2 On The Effects of Sampling Rate and Interpolation in HMM-Based Dynamic Signature Verification Curitiba, Parana, Brazil September 23-September 26 ISBN: 0-7695-2822-8
In this work, resampling techniques and interpolation are applied to on-line signatures. Their effect on the perfor- mance of an on-line signature system using Hidden Markov Models is studied. The presented techniques are based on linear interpolation and Catmull-Rom cubic splines. Exper- imental results are provided on the MCYT database com- prising 16,500 signatures from 330 subjects and as many skilled forgeries. Our approach allows to reduce the sam- pling rate of the on-line signature capture system, leading to the reduction of storage resource requirements and in- creased simplicity without compromising and even enhanc- ing the system performance. This also leads to the discus- sion of which is the minimum sampling rate for HMM-based dynamic signature verification.
