Eigenface classification using an extended kernel-based nonlinear discriminator
Benyong Liu, Bing Yu Liu, Xin Sun, Jing Zhang · 2004
This paper extends a kernel-based nonlinear discriminator (KND) to a new version by an oblique projection realization and applies it to eigenface classification. In an extended KND, the effect of the target class on the performance of a classifier is considered. Experimental results on the ORL face database demonstrate the effectiveness of an eKND in face recognition.
