  As the evolution of multiview display technology is bringing glasses-free
3DTV closer to reality, MPEG and VCEG are preparing an extension to HEVC to
encode multiview video content. View synthesis in the current version of the 3D
video codec is performed using PSNR as a quality metric measure. In this paper,
we propose a full- reference Human-Visual-System based 3D video quality metric
to be used in multiview encoding as an alternative to PSNR. Performance of our
metric is tested in a 2-view case scenario. The quality of the compressed
stereo pair, formed from a decoded view and a synthesized view, is evaluated at
the encoder side. The performance is verified through a series of subjective
tests and compared with that of PSNR, SSIM, MS-SSIM, VIFp, and VQM metrics.
Experimental results showed that our 3D quality metric has the highest
correlation with Mean Opinion Scores (MOS) compared to the other tested
metrics.
