9-6 Real-time eye-direction classification scheme robust against head pose variation for visual interface

Abstract

We built a visual interface system in which automatic eye-direction classification robust against head pose variation was achieved by acquiring the 3D posture information of the face by means of a state-of-the-art head tracking software, faceAPI. We made a comparison between several feature extraction schemes for representing the local image pattern around the eyes in terms of validity in discriminating eye directions.
