PASSIVE DRIVER GAZE TRACKINGWITH ACTIVE APPEARANCE MODELS

摘要

Monocular gaze estimation is usually performed by locating the pupils, and the inner andouter eye corners in the image of the driver's head. Of these feature points, the eye cornersare just as important, and perhaps harder to detect, than the pupils. The eye cornersare usually found using local feature detectors and trackers. In this paper, we describe amonocular driver gaze tracking system which uses a global head model, specifically an ActiveAppearance Model (AAM), to track the whole head. From the AAM, the eye corners,eye region, and head pose are robustly extracted and then used to estimate the gaze.
