fingerprint-matching

fingerprint-matching is a Python library for matching fingerprints.

Fingerprint Features

Ridges - where the skin has a higher profile than its surroundings (BLACK)
Valleys - where the skin has a lower profile than its surroundings (WHITE)
Directional field (DF) - local orientation of the ridge-valley structures (VECTOR FIELD)
The singular points (SPs) - discontinuities in the directional field (CORE, DELTA)
Minutiae - details of the ridge-valley structures (RIDGE ENDINGS, BIFURCATIONS)
Directional field is used for enhancement of the fingerprint
Directional field + The singular points is used for classification
Minutiae is used for matching

Steps

1. Feature Extraction

1. • Directional field estimation

2. • Singular point Extraction
3. • Segmentation of fingerprint
4. • Minutiae Extraction

2. Matching

3. Database Search
