Adaptive Score Normalization: A Novel Approach For Multimodal Biometric Systems

Anouar Ben Khalifa, Sami Gazzah & Najoua Essoukri BenAmara
Multimodal biometric systems integrate the data presented by multiple biometric sources, hence offering a better performance than the systems based on a single biometric modality. Although the coupling of biometric systems can be done at different levels, the fusion at the scores level is the most common since it has been proven effective than the rest of the fusion levels. However, the scores from different modalities are generally heterogeneous. A step of normalizing the scores...
