Abstract

Indexing large fingerprint databases is an important and challenging problem. In this paper, an invariant-based fingerprint indexing scheme is proposed. Minutia and surrounding ridges are combined to form a substructure. The invariants describe binary relations between substructures. Experimental results on FVC2002 database demonstrate the validity of the proposed algorithm.
