Estimating quality of experience on stereoscopic images

Stereo quality of experience (QoE) can be affected by many factors in three-dimensional (3D) media. We pay our attention to three main factors, namely scene content, camera baseline, and screen size, which were found to be the most significant influencing factors from our previous subjective tests. In order to estimate the QoE on stereoscopic presentations, this paper proposes a perceptual quality metric by characterizing these three factors using image disparity plus additional weights on screen size. The experimental results demonstrate that the proposed metric can achieve more than 87% correlation with subjective scores, which is better than the traditional two dimensional (2D) metrics without integrating 3D characteristics, with the ground truth of QoE from our subjective tests and a publicly available stereoscopic quality database.
