A Two-Stage Fusion Scheme using Multiple Fingerprint Impressions

In this paper, we propose a two-stage fusion scheme that takes full advantage of the complementary information among multiple fingerprint impressions. While comparing the query fingerprint with a template impression, all the other impressions are also transformed using the 2D warping model to register with the query fingerprint so that the additive matched minutiae pairs can be detected to improve the matching result with a subset combination scheme. Then a matching score level fusion or decision level fusion is performed to integrate the improved matching results corresponding to different impressions. Experiments conducted on FVC2002 show that the proposed method produces a much better performance for fingerprint matching.
