A new reference point for fingerprint recognition
K. Rerkrai, Vutipong Areekul · 2000
A new reference point for fingerprint recognition called a focal point is proposed. The focal point is an expected focus of curved ridges of fingerprint images. The focal point is designed as a center of moment in polar coordinate for the fingerprint matching method. The focal point for any type of fingerprint images can be identified and tested with various orientation, elastic distortion and noise. The results are very promising for fingerprint recognition applications.
