Fingerprint matching is affected by the nonlinear distortion introduced in fingerprint impressions during the image acquisition process. This nonlinear deformation causes fingerprint features such as minutiae points and ridge curves to be distorted in a complex manner. In this paper we develop an average deformation model for a fingerprint impression (baseline impression) by observing its relative distortion with respect to several other impressions of the same finger. The deformation is… 

Fingerprint warping using ridge curve correspondences

TLDR
Results based on experimental data consisting of 1,600 fingerprints corresponding to 50 different fingers collected over a period of two weeks show that incorporating the proposed deformation model results in an improvement in the matching performance.

Fingerprint Deformation Models Using Minutiae Locations and Orientations

TLDR
The estimated average deformation is used to pre-distort a template prior to matching it with a query image in a verification task and experimental results show that the use of minutiae locations and orientations to estimate the deformation leads to a more representative deformation model than using minUTiae locations only.

A Combined Radial Basis Function Model for Fingerprint Distortion

TLDR
A combined radial basis function (RBF) model, which separately builds rigid and nonrigid transformations, for attacking the distortion problem is proposed, which provides more accurate mapping function between a possible matched-pair.

Fingerprint registration by maximization of mutual information

TLDR
A new algorithm for fingerprint registration using orientation field is proposed, which finds the correct alignment by maximization of mutual information between features extracted from orientation fields of template and input fingerprint images.

Data Acquisition and Processing of 3-D Fingerprints

TLDR
A noncontact fingerprint scanner employing structured light illumination to generate high-resolution albedo images as well as 3-D ridge scans is introduced to solve the problems associated with conventional 2-D fingerprint scanners such as skin deformation and print smearing.

Averaging of Fingerprint Template with Respect to Elastic Deformations

The paper describes a technique of generation of an “undeformed”, i.e. averaged with respect to elastic deformations, fingerprint template. We offer to calculate the average “undeformed” fingerprint

Latent fingerprint recognition and categorization using Multiphase Watershed Segmentation

TLDR
This research work proposes Multiphase Watershed Segmentation algorithm to refine the features collected from the poor quality fingerprint impression to improve the matching accuracy of latent fingerprints which are of bad quality.

TLDR
This paper presents a novel approach to detect and estimate distortion occurring in fingerprint video streams, and directly works on MPEG-{1, 2} encoded fingerprint video bitstreams to estimate interfield flow without decompression, and uses flow characteristics to investigate temporal behaviour of the fingerprints.

Improved Fingerprint Matching by Distortion Removal

TLDR
The novel approach presented here corrects distortions in fingerprints that have already been acquired, and results are presented demonstrating significant improvements in matching accuracy through the application of the technique.

TLDR
It is shown that simple steps in image acquisition can enhance the system performance vastly and compensate for scaling, translation, rotation and structural distortions of the fingerprint minutiae features due to skin elasticity.

Distortion-tolerant filter for elastic-distorted fingerprint matching

TLDR
This paper gives results for using distortion tolerant filters to improve performance of fingerprint correlation matching, and shows performance was improved from 49% correct, using one training fingerprint, to 100%correct, using multiple training fingerprints, and a distortion- tolerant MINACE filter, with no false alarms.

On-line fingerprint verification

TLDR
An improved minutia extraction algorithm that is much faster and more accurate than an earlier algorithm has been implemented and an alignment-based elastic matching algorithms has been developed for minutian matching.
