Color face recognition based on NMF with Fisher rule

Color face provides more cues for face recognition task than grey scale ones. A novel color face recognition approach based on NMF algorithm with Fisher rule coined Fisher-NMF is proposed in this paper. The approach employs matrix to encode color information of different channels. Fisher discrimination rule is integrated with the non-negative matrix factorization algorithm to extract facial features. Nearest neighborhood classifier is adopted to identify color face samples. Experimental results on CVL and CMU PIE color face databases verify the effectiveness of the proposed approach.
