Executive Summary

3D video is expected to provide an enhanced user experience bringing more realism through depth impression. Therefore, quality assessment plays an important role when designing and optimizing 3D video processing methods and applications. In this paper, the authors propose and validate a novel quality metric based on binocular human visual system. Both visual distortions in the cyclopean view and perceptibility of depth are considered. Visual distortions are analyzed in 3D-DCT domain taking into account the masking effects of the Contrast Sensitive Function (CSF) and depth variability. The metric is especially tailored for mobile 3DTV applications as it takes into account the target display size and resolution and calculates disparity variations in local areas with relevant foveal size.
