22-2 Improvement of pupil detection using head pose detection

Abstract

Pupil detection is useful for human monitoring systems. We detected the pupils by differentiating the bright and dark pupil images which are obtained in every field. This method makes pupil detection dramatically easy. However, when a subject's quickly moves, the method does function well because of the gap between the positions of the bright and dark pupils. This paper proposes the image difference method with positional compensation based on our head pose detection method.
