Abstract :
The paper presents an algorithm for registration and matching criteria in fingerprint based security systems. Topics discussed include: compression of fingerprint images in the spatial domain; local mean histograms; methods of calculating direction vectors; registration point extraction; normalization of the registration area; extraction of ridge bifurcation by Gabor filter; method of generating fingerprint code; database entry; matching criteria for the database. I also discuss two methods, registration point detection and Poincare index method, and explain why the second method is invalid.
