Abstract :
Texture-based automatic face recognition (AFR) methods find global similarities between two faces by computing their local regional similarities. A novel method based on Fisher discriminant analysis is proposed to estimate each region´s contribution to the global similarity score. Experimental results show that the method considerably improves recognition performance for texture-based AFR.
