Databases

Four different databases (DB1, DB2, DB3 and DB4) were collected by using the following sensors/technologies:

  • DB1: optical sensor "TouchView II" by Identix
  • DB2: optical sensor "FX2000" by Biometrika
  • DB3: capacitive sensor "100 SC" by Precise Biometrics
  • DB4: synthetic fingerprint generation

Each database is 110 fingers wide (w) and 8 impressions per finger deep (d) (880 fingerprints in all); fingers from 101 to 110 (set B) have been made available to the participants to allow parameter tuning before the submission of the algorithms; the benchmark is then constituted by fingers numbered from 1 to 100 (set A).

Sensor Type Image Size Set A (wxd) Set B (wxd) Resolution
DB1 Optical Sensor 388x374 (142 Kpixels) 100x8 10x8 500 dpi
DB2 Optical Sensor 296x560 (162 Kpixels) 100x8 10x8 569 dpi
DB3 Capacitive Sensor 300x300 (88 Kpixels) 100x8 10x8 500 dpi
DB4 SFinGe v2.51 288x384 (108 Kpixels) 100x8 10x8 about 500 dpi

The following figure shows a sample image from each database:
