Abstract
Summary form only given. This paper presents a new approach for an eye tracking method considering the spherical geometry of the eye. We use a deformable model and normalized correlation to find the center of a distorted pupil image. Deformation parameters are translation, scaling, and two rotations about the horizontal and the vertical axis. The optimizing method is the Levenberg-Marquardt method. For calculation efficiency, we use a hierarchical search in normalized correlation.
