Скачать или смотреть Pupil and Iris Tracking using a RGB-IR Camera

In this study, we propose a novel eye-tracking method which can track pupil and extract iris area simultaneously using the multispectral camera. The hybrid method has functional advantages in addition to compensating for the weaknesses of each method. The rotation center of the eyeball has been treated as a static point in previous studies, but we can consider the movement of the center of rotation using the result of tracking pupil and iris. Additionally, the diameter of the pupil can be measured quantitatively with a single camera. We conducted two experiments for evaluating the estimated iris area, the detected point-of-gaze, and the computed size of the pupil. When the eye moves to inner corner extremely, we observed that the error is increased in the case of using the previous method. In contrast, we confirmed the effectiveness of the proposed method which considers the movement of the rotation center through experiments.
