Direct Pore Matching for Fingerprint Recognition

Abstract: Abstract. Sweat pores on fingerprints have proven to be useful features for personal identification. Several methods have been proposed for pore matching. The state-of-the-art method first matches minutiae on the fingerprints and then matches the pores based on the minutia matching results. A problem of such minutia-based pore matching method is that the pore matching is dependent on the minutia matching. Such dependency limits the pore matching performance and impairs the effectiveness of the fusion of minuti… Show more

“…Here, we will use the same local descriptors as in [7] for pores so that we can fairly compare the performance of SR-based and correlationbased approaches. The local descriptor N R p ∈ of a pore as defined in [7] essentially captures the intensity variation in a circular neighborhood to the pore. To calculate the differences between pores, we will use the SR-based rather than correlation-based technique.…”

“…The goal of this refinement step is thus to eliminate these false pore correspondences from the obtained coarse pore correspondences. The difference between the method we use here and the method in [7] is that when applying RANSAC, we choose pore correspondences according to the differences between the pores in the correspondences such that the pore correspondences with smaller differences will be chosen with higher probability than those with larger differences. That is we employ the WRANSAC algorithm [8] to refine pore correspondences.…”
