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. (Published abstract provided)
