Abstract

A method of face recognition based on the second-order statistics (SOS) is proposed and an optimal size of feature space of the SOS is determined by experiments. Experimental results show that the correct recognition rate of 97.1% is obtained for 91 subjects. The frontal face recognition system is then compared with a profile recognition system based on the P-Fourier descriptor. For input patterns without rotations/inclinations, the frontal face recognition system achieved higher recognition rate than that of profiles. However, for input images with tilts, the profile recognition system performed higher accuracy than that of frontal faces.
