Image mosaicing for rolled fingerprint construction
Nalini Ratha, Jonathan H. Connell, Ruud M. Bolle · 2002
With the use of inkless scanners as input devices for acquiring fingerprints of a person, the digital image of the finger is restricted to the area in contact with the sensor The conventional method of fingerprint image acquisition involves obtaining a nail-to-nail image of the finger known as the rolled fingerprint impression. We present a method of constructing a rolled fingerprint from an image sequence of partial fingerprints using a live-scan fingerprint imager.
