The stereoscopic three-dimensional (3D) video technologies have achieved significant success in providing enhanced immersive experience to consumers. However network delivery of 3D video content at good quality levels is challenging mostly due to the variable network conditions. In this context, efficient objective 3D video quality assessment is a critical aspect, in particular for video service providers who need to adjust the video delivery process to the network conditions in real-time. Current objective 3D video quality assessment methods are reference-based, requiring the availability of the original 3D video sequences, which is difficult to achieve in practice. Additionally, most of the existing 3D video quality metrics are developed for depth-enhanced 3D. This paper proposes the No reference objective Video Quality Metric (NVQM) for real-time 3D video quality assessment. NVQM considers the correlation …
