3D TOUCHLESS FINGERPRINTS: COMPATIBILITY WITH LEGACY ROLLED IMAGES
3D TOUCHLESS FINGERPRINTS: COMPATIBILITY WITH LEGACY ROLLED IMAGES
Fingerprints are traditionally captured based on contact of the
finger on paper or a platen surface. This often results in partial
or degraded images due to improper finger placement, skin
deformation, slippage and smearing, or sensor noise from wear
and tear of surface coatings. A new generation of touchless
live scan devices that generate 3D representation of fingerprints
is appearing in the market. This new sensing technology
addresses many of the problems stated above. However,
3D touchless fingerprint images need to be compatible with
the legacy rolled images used in Automated Fingerprint Identification
Systems (AFIS). In order to solve this interoperability
issue, we propose a unwrapping algorithm that unfolds the
3D fingerprint in such a way that it resembles the effect of
virtually rolling the 3D finger on a 2D plane. Our preliminary
experiments show promising results in obtaining touchless
fingerprint images that are of high quality and at the same
time compatible with legacy rolled fingerprint images.
