Polarization-enhanced invariant fingerprint verification/identification system

We have previously shown that polarization enhancement of fingerprint images during the enrolment process improves the performance of the verification and identification processes. In this paper, we present a design and analysis of a new synthetic discriminant function (SDF) for rotation/scale invariant polarization-enhanced fingerprint system. Performance comparison between the proposed SDF and an SDF obtained for traditional fingerprint systems is included.
