Description
NIST Special Database 300 contains digitized images from 888 inked fingerprint arrest cards. The database includes 10 rolled impressions, two four-finger slap impressions, two thumb slap impressions, and segmented impressions from slap images, scanned at 500, 1,000, and 2,000 pixels per inch. Data was created by NIST in collaboration with the FBI and was available as of July 2018.
Use Cases
Train image segmentation models using the provided coordinates to isolate individual fingerprint impressions from slap images.
Analyze the quality and condition of rolled fingerprint impressions across cards ranging from pristine to badly damaged.
Benchmark fingerprint recognition algorithms on 888 cards containing impressions at three distinct scanning resolutions (500, 1,000, 2,000 PPI).
Study the characteristics of four-finger slap and thumb slap impressions for biometric template creation.
Strengths
Contains 888 distinct fingerprint cards, providing a foundation for biometric analysis.
Offers images scanned at three specific resolutions: 500, 1,000, and 2,000 pixels per inch.
Includes multiple impression types: 10 rolled, two four-finger slap, two thumb slap, and segmented impressions.
Limitations
The dataset size is limited to 888 cards, which may be insufficient for training large-scale deep learning models.
Cards vary in physical condition from pristine to badly damaged, introducing label noise for quality assessment tasks.
As of the description, only the 500 PPI PNG data (Special Database 300a) was confirmed available; other formats and resolutions may not be accessible.
