Quality evaluation of 3D video using colour-plus-depth & MDC over IP networks

This paper studies the quality evaluation of three-dimensional col-our-plus depth videos over error prone IP networks. Scalable and multiple-description coding techniques are utilized for transmis-sion. In order to study the impact of packet losses to the perceived 3D video quality, path diversity is characterized by asymmetric packet losses. Mean Opinion Score (MOS) for the multiple de-scription scheme is affected by both the encoding parameters and the sensed packet loss rate at each 3D description. Moreover, the effect of 3D video reconstruction through interpolation using a single, reliably delivered description has been compared against using all delivered descriptions, and it is found out that subject´s rate the 3D videos reconstructed using a single descriptions higher scores under severe packet loss rate conditions.
