Quality assessment of 3D asymmetric view coding using spatial frequency dominance model

Abstract

To save bit-rate in stereo video application, asymmetric view coding is introduced, which encodes the stereo views with different qualities. However, quality assessment on asymmetric view coding is difficult, because the impact of the degraded view upon the 3D percept depends on Human Visual System (HVS) and cannot be indicated by conventional metrics. This paper introduces a quality assessment model based on the observed phenomenon that spatial frequency determines view domination under the action of HVS. A metric is proposed based on this model for assessing the quality of asymmetric view coding. Experimental results are presented to show that the proposed metric provides accordant assessment with the subjective evaluation.
