Optimal Gabor filters for high speed face identification

This paper describes a fast face identification method with Gabor filters. Two efforts are made to achieve the acceptable processing speed: 1) we design the optimal Gabor filters with the arrangement theory that uses a few directions and layers; and 2) the transformation with Gabor filters (called Gabor transformation) is only done over the regions around the facial feature points, not the whole input image. The facial feature points extraction is performed by detecting the facial organ regions with color information and edge information, followed by, the corner detection in each detected facial organ region with the SUSAN operator.
