Abstract:
A pupil detecting apparatus detects an edge of a pupil in an image of a face. An outline of an upper eyelid is also detected. The apparatus selects an effective edge extending along the pupil by removing a part of edge extending along the upper eyelid from the edges detected. Then, the apparatus applies the circle Hough transformation to the effective edge in order to obtain a center of the pupil and a radius of the pupil. Thereby, it is possible to detect the pupil accurately even if a part of the pupil is covered.
