ABSTRACT:
A fingerprint symmetry axis extraction method is provided. The method includes detecting a core point of a fingerprint, setting imaginary symmetry axes intersecting the core point, and extracting an actual fingerprint symmetry axis from the imaginary symmetry axes. The actual fingerprint symmetry axis is one that can provide the largest symmetry measure being obtained between ridge range directions in paired blocks facing each other.
