A discussion on fusion/confusion at score level in unimodal biometric systems

Fusing biometric information at different levels is one of the widely-preferred techniques for better accuracy. Researchers attempt to decrease error rates by fusing either multiple biometrics or apply sensor-, feature-, score- or decision-level fusion in unimodal biometric systems. Although it incr...

Description
Summary:Fusing biometric information at different levels is one of the widely-preferred techniques for better accuracy. Researchers attempt to decrease error rates by fusing either multiple biometrics or apply sensor-, feature-, score- or decision-level fusion in unimodal biometric systems. Although it increases the complexity of systems, fusion works usually well. However, in some cases score-level fusion may degrade the performance instead of improving the system. In this study a discussion on fusion whether it causes confusion or not is raised by presenting a unimodal face fusion approach. Results show that if fusion is not designed properly, it may cause confusion.
