A novel quality assessment of transmitted 3D videos based on binocular rivalry impact

摘要

Binocular rivalry, a challenging visual phenomenon occurs frequently for dissimilar monocular stimuli in 3D video communication particularly in error concealment. The quality assessment of distorted 3D video is a crucial element in designing and arranging advanced immersive media distribution platforms. In this paper we propose a quality assessment (QA) criterion that can be measured by considering the correlation of binocular rivalry impact. At first, subjective assessment is done for different frame freezing stereoscopic error concealment techniques and is compared with 2D to approximate the binocular rivalry characteristics. Secondly, a QA approach is proposed based on the perceptual characteristics of the Human Visual System (HVS). Finally, by incorporating the approximation with the perceptual measure, an assessment metric is generated for the transmitted 3D videos. Experimental analysis with common video datasets and comparison with different algorithms shows the efficiency of the proposed algorithm for video that is affected by asymmetric distortion and so is subject to binocular rivalry for stereoscopic views.
