Abstract: In recent years numerous algorithms have been proposed for face recognition [1] and much progress has been made toward this direction. Most of these algorithms achieve high rates of correct recognition only under very small variations in illumination, scale, facial expressions and perspective angle or pose transformations [2, 3]. The inefficiency of the presented algorithms under extreme variations of the above factors is quite reasonable. Recent investigations have shown that the proposed face representation schemes derive greater variability in a given face under changes in scale, illumination, perspective angle and expression, than different faces when these three factors are held constant. In other words intra-class variance is larger than the inter-class one [2].
