Abstract

In this paper, we compare two correlation techniques for face recognition. An optical correlator using the Binary Phase-Only Filter (BPOF) was simulated and tested on a database of faces. Its performance is compared with that of an extended correlation method suggested by Kyatkin and Chirikjian. The results are compared in terms of the number of false positives. For our tests and for both methods we use the challenging AT&T database of images with varying facial illuminations, facial expressions, and pose. We show how, from the accuracy point of view, the extended correlation method outperforms the BPOF.
