Dataset Description

In this competition, a new database called "Latent Fingerprint In the Wild Database (LFIW) [1]" is used for performance evaluation under real-world scenarios with high image quality. The LFIW database consists of six subsets of which two subsets are traditional fingerprints, three latent fingerprints and one fingerphoto set, as provided below:

1. R-opt: Reference fingerprints from optical sensor;

2. R-cap: Reference fingerprints from capacitive sensor;

3. Smt: Smartphone fingerphotos;

4. L-wall: Latent fingerprints captured from wall surface;

5. L-ipad: Latent fingerprints captured from Ipad surface;

6. L-alum: Latent fingerprints captured from aluminum foil surface.

Detailed information of the LFIW database is further provided in the table below.
