Under this approach, the number of states and Gaussians giving the optimal prediction results are independently selected for each user. With this simple strategy just three genuine signatures could be used for training, with an EER under 2.5% obtained for the basic set of raw signature parameters provided by the acquisition device. This results increment by a factor of six the accuracy obtained with the typical approach in which claim-independent structure is used for the HMMs. PB Springer SN 978-3-540-74549-5 YR 2007 FD 2007 LK http://uvadoc.uva.es/handle/10324/41029 UL http://uvadoc.uva.es/handle/10324/41029 LA eng NO Lee, S.W.; Li, S.Z.
