Feature extraction and location of eye are very important in face expression recognition, human-computer interaction, face detection and identification etc. This paper presents a new efficient method for eye location. Firstly, gradient, integral image, and Hough transform are used to obtain location and radius of the pupil. Secondly, CANNY operator and ellipse fitting of direct least square are used to obtain elliptic equation of the eyelid. Finally, the center of the ellipse is deemed to bedoi:10.4304/jsw.9.2.319-323 fatcat:gywph3ukl5bbdnyt4ca4mlz4he
