The Bayes Decision Rule Induced Similarity Measures
June 2007 (vol. 29 no. 6)
pp. 1086-1090
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.
Index Terms:
Face Recognition Grand Challenge (FRGC), PRM Whitened Cosine (PWC) similarity measure, whitened cosine similarity measure, Within-Class Whitened Cosine (WWC) similarity measure.
