This paper presents a simple color based segmentation technique for faces. The proposed technique utilizes saliency maps and incorporates both top-down (data driven) and bottom-up saliency methods to generate the saliency map used in the segmentation phase. The top-down approach uses skin color data obtained from a training database to bias the skin color saliency map while the bottom-up approach utilizes both the intensity and color features maps from the test image. The saliency map is computed from the center sound difference and normalization of the feature maps from both systems. Finally, a square moving window function is used to determine the point with the highest energy in the saliency map, which is marked as the facial region. The system shows good performance for subjects in both simple and complex backgrounds, as well as varying illumination conditions and skin color variances.
