On the study about opening and closing of an eyelid-application to the support system of medical care

Abstract

Bedridden persons who cannot use their hands, mouth or ears communicate with other persons only by opening and shutting their eyelids. Hence a communication support system for such persons is important and necessary. The purpose of this paper is to design a system to estimate whether an eyelid is open or shut from a sequence of real images which are taken with a CCD camera.
