Paper Abstract

In this paper, we study the effect of illumination on face recognition. The challenging database of images created by AT&T Laboratories Cambridge has been used for all our tests. Since images of the same individual in the database have been taken under varying light sources, illumination across the images is not uniform. We pre-processed all the database images for non-uniform illumination correction. Correlation tests were performed on these pre-processed images using two methods - first, by simulating a simple correlator employing the Binary Phase Only Filter (BPOF) and second, using the extended correlation method suggested by Kyatkin and Chirikjian. Results are presented to show the effect of illumination correction on both methods.
