Singular point detection in fingerprints using quadrant change information

Automatic localization of singular points in fingerprints is of critical importance in many algorithms. Existing methods of detecting singular points often require tedious ad-hoc parameter tuning, particularly in the presence of degraded quality fingerprints. In this paper we present an approach towards singular point detection in fingerprints that operates on the quadrant change information and is largely insensitive to the degradation of fingerprint quality
