NIST Special Database 14 is being distributed for use in development and testing of automated fingerprint classification and matching systems on a set of images which approximate a natural horizontal distribution of the National Crime Information Center (NCIC) fingerprint classes and were compressed using an implementation of the wavelet scalar quantization (WSQ) compression specification.

The database consists of one zip file containing 54,000 fingerprint images and corresponding metadata TXT files.

Each segmented image is 832 by 768 pixels and classified using the NCIC classes given by the FBI.

 NIST Special Database 14 has the following features:

·27,000 pairs of segmented 8-bit gray scale fingerprint images

·Images compressed with an implementation of the WSQ compression specification

·NCIC classifications given by the FBI

·Cards selected randomly thus approximating the natural horizontal distribution of the NCIC classifications.

·Scanned at 19.7 pixels per mm.

·The fingerprint images are the same as the Portable Network Graphics (PNG) images in NIST Special Database 9.

Suitable for automated fingerprint classification research, the database can be used for:

·algorithm development

·system training and testing

The database is a valuable tool for evaluating fingerprint systems using a statistical sample of fingerprints which approximate a natural horizontal distribution of the NCIC classifications and were compressed with an implementation of the WSQ compression specification.
