title: The Bayes decision rule induced similarity measures.
abstract: This paper first shows that the popular whitened cosine similarity measure is related to the Bayes decision rule under specific assumptions and then presents two new similarity measures: the PRM Whitened Cosine (PWC) similarity measure and the Within-Class Whitened Cosine (WWC) similarity measure. Experiments on face recognition using the Face Recognition Grand Challenge (FRGC) version 2 database show the effectiveness of the new measures.
