Do you know if the matching algorithm used for Fingerprint could also be used for the FingerVein?
Matching algorithm currently exclusively uses minutiae for matching. Since minutiae can be identified on finger veins too, it is in theory possible to force SourceAFIS to match finger vein templates after appropriate template format conversion. Accuracy is likely to be very poor though. It would take some parameter tuning and perhaps some algorithm modifications to make it work well. Extraction algorithm on the other hand is thoroughly incompatible with finger veins.
