Performance Evaluation

For each database and for each algorithm:

  • Each sample in the subset A is matched against the remaining samples of the same finger to compute the False Non Match Rate FNMR (also referred as False Rejection Rate - FRR). If the matching g against h is performed, the symmetric one (i.e., h against g) is not executed to avoid correlation. The total number of genuine tests (in case no enrollment rejections occur) is:
    ((8*7) /2) * 100 = 2,800
  • The first sample of each finger in the subset A is matched against the first sample of the remaining fingers in A to compute the False Match Rate FMR (also referred as False Acceptance Rate - FAR). If the matching g against h is performed, the symmetric one (i.e., h against g) is not executed to avoid correlation. The total number of false acceptance tests (in case no enrollment rejections occur) is:
    ((100*99) /2) = 4,950

For each algorithm and for each database, the following performance indicators are reported:

  • REJENROLL (Number of rejected fingerprints during enrollment)
  • REJNGRA (Number of rejected fingerprints during genuine matches)
  • REJNIRA (Number of rejected fingerprints during impostor matches)
  • Impostors and Genuines distributions
  • FMR(t)/FNMR(t) curves
  • ROC(t) curve
  • EER (equal-error-rate)
  • EER* (the value that EER would take if the matching failures were excluded from the computation of FMR and FNMR)
  • FMR100 (the lowest FNMR for FMR<=1%)
  • FMR1000 (the lowest FNMR for FMR<=0.1%)
  • ZeroFMR (the lowest FNMR for FMR=0%)
  • ZeroFNMR (the lowest FMR for FNMR=0%)
  • Average enrollment time
  • Average matching time

The following average performance indicators are reported over the four databases:

  • Average EER
  • Average FMR100
  • Average FMR1000
  • Average ZeroFMR
  • Average REJENROLL (Average number of rejected fingerprints during enrollment)
  • Average REJMATCH (Average number of rejected fingerprints during genuine and impostor matches)
  • Average enrollment time
  • Average matching time
