Effectiveness of Score Normalisation in Multimodal Biometric Fusion

An important problem which can adversely influence the overall effectiveness of biometric recognition is the undesired variations in the biometric data. This is because such variations are reflected in the corresponding biometric scores. This paper investigates the effectiveness of different score normalization techniques for tackling this issue as well as enhancing the accuracy of multimodal biometrics. The fusion process is accomplished at the score level.
