Fingerprint SDK Library for Linux

Fingerprint segmentation, Quality Assessment, Encoding and Matching.

Fingerprint SDK Library

Our fingerprint SDK, provides several key features which makes working with fingerprints easy. Fingerprint segmentation, Quality Assessment, Encoding and Matching. Our fingerprint encoder supports generating templates using ANSI INCITS 378-2004, ANSI INCITS 378-2009 and ANSI INCITS 378-2009 amendment 1 standards. Many pieces of information are used during matching including minutia location, ridge flow, ridge counts, classifications, core and deltas. Our SDK provide easy 1-1 or 1-many matching functions.

Key features

Biometric Solutions Provider

Net-X Solutions are a cutting edge biometric solutions provider, our solutions are in use worldwide, securing data and personnel.

1

Fingerprint Segmentation

Detect and segment fingerprints. Both the segmented image and its location within the source image are provided enabling you to apply an optional overlay to show the placement of the segments.

2

Fingerprint Quality Assessment

The NFIQ (NIST Fingerprint Image Quality) of a fingerprint image can be determined providing a score from 1 to 5.

3

Halo Removal

Analyse and remove the presence of the "Halo Effect" from a fingerprint image, The Halo Effect is caused by condensation from the placing of warm, moist fingers on a colder platen of a Livescan optical scanner. By removing the Halo effect you can greatly improve the accuracy of segmentation and quality checks.
