In order to overcome this shortcoming, an improved gray-level integration projection method in the polar coordinates is proposed. Face regions are extracted from the image by the feature of skin color. Gray-level integration is projected to the polar angle in the face region to detect the angles of eyes. Pixels in the direction of eyes are projected to the horizontal direction to determine the position of eyes. The method can detect eyes from several different posture faces in the same image. A lot of simulation results show that the detection performance of the method has good robustness to the rotational variation of face. Thus, the method can expand the eye detection application of gray-level integration projection method. %U http://cea.ceaj.org/EN/abstract/article_33350.shtml
