Image Mosiacing for Rolled Fingerprint Construction (2009)
Nalini K. Ratha, Jonathan H. Connell, Ruud M. Bolle
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...
FACE RECOGNITION AND ITS APPLICATIONS (2009)
Andrew W. Senior, Ruud M. Bolle
Face recognition has long been a goal of computer vision, but only in recent years reliable automated face recognition has become a realistic target of biometrics research. New algorithms, and...
Lecture Notes in Computer Science 1 Fingerprint Minutiae: A Constructive Definition (2007)
Ruud M. Bolle, Andrew W. Senior, Nalini K. Ratha, Sharath Pankanti
Abstract. The flow pattern of ridges in a fingerprint is unique to the person in that no two people with the same fingerprints have yet been found. Fingerprints have been in use in forensic...

Nalini K. Ratha, Andrew Senior, Ruud M. Bolle
Identity verification becomes a challenging task when it has to be automated with high accuracy and non-repudiability. The existing methods such as passwords and photo identity cards are inadequate...
An analysis of minutiae matching strength (2001)
Nalini K. Ratha, Jonathan H. Connell, Ruud M. Bolle
In recent years there has been exponential growth in the use of biometrics for user authentication applications because biometrics-based authentication offers several advantages over knowledge and...
Robust fingerprint authentication using local structure similarity (2000)
Nalini Is. Ratha, Ruud M. Bolle
bolle @ us.ibm.com Fingerprint matching is challenging as the matcher has to minimize two competing error rates: the False Accept Rate and the False Reject Rate. We propose a novel, ef-ficient,...

Evaluation Techniques for Biometrics-based Authentication Systems (FRR (2000)
Ruud M. Bolle, Sharath Pankanti, Nalini K. Ratha
Biometrics-based authentication is becoming popular because of increasing ease-of-use and reliability. Performance evaluation of such systems is an important issue. We attempt to address two aspects...
Computing Reflectance Ratios from an Image (1993)
This paper presents a photometric invariant called reflectance ratio that can be computed from a single brightness image of a scene. The brightness variation in an image of a surface depends on...
