Modified F score normalization method of multi-modal biometric recognition

A novel score normalization algorithm, named MF normalization, is presented. The MF normalization algorithm can consider the client and impostor score distributions, and the relationship of different expert score distributions simultaneously. The MF normalization will be of fewer parameters to estimate, and is easy to implement. The simulation results on XM2VTS multimodal database show that the proposed algorithm is of satisfactory performance.
