RT info:eu-repo/semantics/article T1 Optimization of a Biometric System Based on Acoustic Images A1 Izquierdo Fuente, Alberto A1 Del Val Puente, Lara A1 Villacorta Calvo, Juan J. A1 Raboso Mateos, Mariano AB On the basis of an acoustic biometric system that captures 16 acoustic images of a person for 4 frequencies and 4 positions, a study was carried out to improve the performance of the system. On a first stage, an analysis to determine which images provide more information to the system was carried out showing that a set of 12 images allows the system to obtain results that are equivalent to using all of the 16 images. Finally, optimization techniques were used to obtain the set of weights associated with each acoustic image that maximizes the performance of the biometric system. These results improve significantly the performance of the preliminary system, while reducing the time of acquisition and computational burden, since the number of acoustic images was reduced.
