This might be caused by missing finger positions in either enrolled user or the probe user. If fingerprints are registered with position "unknown" (instead of e.g. right thumb or left index), IDKit SDK is forced to compare every finger in probe user with every finger in database user for a total of 10x10 = 100 fingerprint comparisons. If you set finger position correctly in both the database and the probe user, only corresponding fingerprint pairs (e.g. right thumb in probe only with right thumb in database) are compared for a total of 10 fingerprint comparisons.
Why does it take longer to search 100 10-fingerprint users than 1000 1-fingerprint users? Print
