An enhanced ultrasound technique for 3D palmprint recognition

In the present work, and enhanced ultrasound technique for extracting 3D palmprint for biometric recognition purposes is presented. The ULtrasound Advanced Open Platform (ULA-OP) is employed as ultrasound imaging system. A commercial high frequency (12 MHz) linear array is moved in the elevation direction by an automated scanning system based on numeric controlled pantograph, which guarantees stable and repeatable measurements. The 3D data are then acquired and elaborated in MATLAB environment to provide several renderings of the 3D palmprint. The experimental results are compared with those acquired with conventional techniques
