Information fusion has been recognized as an important component in the design and implementation of multibiometric systems. Recently, improved matching and recognition performance have been reported in the literature for multimbiometric systems. Information fusion plays a major role in such systems. In fact, for multibiometric systems, information fusion can be viewed as a scheme to improve the quality of the biometric trait sample for more accurate matching performance and reduced false accept/reject rates. It is worth noting that the application of information fusion encompasses several...
