A perceptual quality metric for stereoscopic crosstalk perception
Compared to metrics proposed to assess the quality of two-dimensional (2D) images, there are very few metrics devoted to quality assessment of stereoscopic presentations. Crosstalk is one of the most annoying distortions in the visualization stage of stereoscopic imaging technology. This paper proposes a perceptual quality metric which takes characteristics of stereoscopic images into account for predicting quality levels of crosstalk perception in stereoscopic images, based on an understanding of three main factors, crosstalk level, camera baseline and scene content. The experimental results demonstrate that the proposed metric has Pearson correlation of 87.7% when compared to the ground truth results from the subjective experiments on the crosstalk perception, which is much better than the traditional 2D metrics without integrating 3D depth information.
