The purpose of this paper is to investigate the correlation among the best state of art algorithms for fingerprint verification presented at Fingerprint Verification Competition FVC2004.
For this work, the matching results of more than 40 fingerprint systems from both academy and industry are available on standard benchmark.
The paper shows that the fusion among some competitors of FVC2004 permits a drastically reduction of the performance. Surprisingly, correlation between best performing algorithms is very low, that is, algorithms tend to make different errors: this indicated there is still much room for improvements.
The results of this paper confirm that a multi‐matcher system can overcome some of the limitations of a single matcher resulting in a substantial performance improvement.
The paper tests the fusion among the state‐of‐the‐art practitioners in fingerprint matching (the competitors of FVC2004).
