A Deep Learning Approach to Appearance-Based Gaze Estimation under Head Pose Variations

In this paper, we propose a deep learning based gaze estimation algorithm that estimates the gaze direction from a single face image. The proposed gaze estimation algorithm is based on using multiple convolutional neural networks (CNN) to learn the regression networks for gaze estimation from the eye images. The proposed algorithm can provide accurate gaze estimation for users with different head poses, since it explicitly includes the head pose information into the proposed gaze estimation framework. The proposed algorithm can be widely used for appearance-based gaze estimation in practice. Our experimental results show that the proposed gaze estimation system improves the accuracy of appearance-based gaze estimation under head pose variations compared to the previous methods.
