Effect of difference in 2D video quality for left and right views on overall 3D video quality

Multi-view coding is expected to be used in next-generation encoders and decoders for stereoscopic video services. In multi-view coding, the bit rate for the right eye view is lower than that for the left eye view because the right view is encoded using inter-view technology. In addition, the right view is encoded at a much lower bit rate on the basis of binocular suppression. As a result, the video quality for the left view can be different from that for the right view. We explore here how such a video quality difference between the left and right views affects the overall 3D video quality. In addition, we model the quality characteristics. We conducted a subjective quality assessment to derive subjective quality characteristics. We show that the difference in 2D video quality between the left and right views has little influence on the overall 3D video quality and that the overall 3D video quality can be modeled using the 2D video quality for left and right views.
