gaze estimation,shape from motion,eyeball structure


We propose a method of gaze estimation allowing head motion by an uncalibrated monocular camera. The paper describes dynamic 3-D structure related to eyeball motion in addition to static 3-D structure of SfM(shape from motion). It enables us to detect the influences of the eyeball motion on the image obser vations and estimate the eyeball motion. Assuming that the gaze is considered as a result of independent motions of the head and the eyeball, a probabilistic view for the gaze estimation is given where a dynami cal converging-connected model of the two motions is introduced. The preliminary test suggests the satis factory results.
