Multimodal fingerprint verification by score-level fusion: an experimental investigation

The score-level fusion approaches for fingerprint verification have been widely investigated. However, this investigation has been performed by studying each approach independently from the others, thus using different acquisition sensors, matching algorithms, fusion rules, and data sets. Due to this strong variability, the literature is lack of an experimental investigation aimed to fairly compare the various approaches. This is the scope of the present paper, from the point of view of the performance improvement especially. In our opinion, this investigation can allow to confirm state-of-the-art results by further experimental evidences.
