Abstract

This paper proposes a two-level fusion strategy for audio-visual biometric authentication. Specifically, fusion is performed at two levels: intramodal and intermodal. In intramodal fusion, the scores of multiple samples (e.g. utterances or video shots) obtained from the same modality are linearly combined, where the combination weights depend on the difference between the score values and a client-dependent reference score obtained during enrollment. This is followed by intermodal fusion in which the means of intramodal fused scores obtained from different modalities are either linearly combined or fused by a support vector machine (SVM). Experimental results based on the XM2VTSDB corpus show that intramodal and intermodal fusion are complementary to each other and that SVM-based intermodal fusion is superior to linear combination.
