Fingerprints feature a ridge pattern with moderately varying ridge frequency (RF), following an orientation field (OF), which usually features some singularities. Additionally at some points, called minutiae, ridge lines end or fork and this point pattern is usually used for fingerprint identification and authentication. Whenever the OF features divergent ridge lines (e.g.\ near singularities), a nearly constant RF necessitates the generation of more ridge lines, originating at minutiae. We… Expand

Global Models for the Orientation Field of Fingerprints: An Approach Based on Quadratic Differentials
TLDR
The proposed quadratic differentials model for orientation fields of fingerprints allows for extrapolation into unobserved regions, and is able to verify analytically Penrose's formula for the singularities on a palm. Expand
A model for fingerprint formation
The uniqueness of fingerprints (epidermal ridges) has been recognized for over two thousand years. They have been studied scientifically for more than two hundred years. Yet, in spite of theExpand
Separating the real from the synthetic: minutiae histograms as fingerprints of fingerprints
In this study we show that by the current state-of-the-art synthetically generated fingerprints can easily be discriminated from real fingerprints. We propose a method based on second order extendedExpand
Filter Design and Performance Evaluation for Fingerprint Image Segmentation
TLDR
A novel factorized directional band pass (FDB) segmentation method for texture extraction based on the directional Hilbert transform of a Butterworth bandpass (DHBB) filter interwoven with soft-thresholding is proposed. Expand
Distribution of epidermal ridge minutiae
The distribution of epidermal ridge minutiae on the distal portion of male human thumbprints has been characterized. For each of 412 thumbprints, a centrally located focal minutia was chosen andExpand

TLDR
A method for studying fingerprint minutiae distribution by analyzing their second order statistical properties is proposed, which has successfully explained and unified various previous research observations and should enlighten the study of fingerprintminutiae pattern modeling. Expand
Fingerprint Image Enhancement: Algorithm and Performance Evaluation
TLDR
A fast fingerprint enhancement algorithm is presented, which can adaptively improve the clarity of ridge and valley structures of input fingerprint images based on the estimated local ridge orientation and frequency. Expand
The finger prints of twins
TLDR
Comparisons between armadillo quadruplets and human twins with respect to integalmentary struetures and study of individual pairs of identical twins as to quantitative resemblances are made. Expand
MCC: A baseline algorithm for fingerprint verification in FVC-onGoing
TLDR
An in-depth error analysis allowed us to point out the weakest points of the original MCC and to design a more effective minutiae pair selection and a more distortion-tolerant relaxation. Expand
Merkel cells and the individuality of friction ridge skin.
TLDR
A model for the formation of FRS patterns that links Merkel cells to the epidermal stress distribution is suggested and why the topology of F RS patterns is indeed unique as the arrangement of pattern defects is sensitive to the initial configuration of Merkel cells is suggested. Expand
