In the present work, an improved ultrasound system for biometric recognition based on 3D Palmprint is proposed and experimentally validated. The system exploits an ultrasound gel pad, placed between the palm of the hand and the probe, as coupling medium, which is practical and non-invasive in real applications. Volumetric images of a region the palm of the hand were acquired and then post elaborated to provide 3D and 2D renderings. The recognition procedure is based on the fusion of a couple of 2D Palmprint images at two different under skin depths. A procedure for extracting main features from the fused image was established and a database composed by 315 samples from 63 volunteers was created. Identification experiments were performed to evaluate system performances. Results have shown the effectiveness of the proposed approach.

Abstract

In the present work, an improved ultrasound system for biometric recognition based on 3D Palmprint is proposed and experimentally validated. The system exploits an ultrasound gel pad, placed between the palm of the hand and the probe, as coupling medium, which is practical and non-invasive in real applications. Volumetric images of a region the palm of the hand were acquired and then post elaborated to provide 3D and 2D renderings. The recognition procedure is based on the fusion of a couple of 2D Palmprint images at two different under skin depths. A procedure for extracting main features from the fused image was established and a database composed by 315 samples from 63 volunteers was created. Identification experiments were performed to evaluate system performances. Results have shown the effectiveness of the proposed approach.
