Interest in 3D video has surged in recent years. However, efforts to improve the quality of compression and transmission schemes are severely hampered by a lack of effective quality evaluation metrics. This is a particularly severe problem for researchers trying to improve the robustness of video transmission to packet loss. Subjective tests for evaluating error robustness present huge requirements in terms of time and resources. To solve this problem, this paper presents a quality metric for 3D video, and evaluates its effectiveness for the measurement of quality in the presence of packet loss. A key feature of the work is the use of depth planes to enable the metric to better model how the Human Visual System (HVS) perceives 3D video. The quality metric results are compared with subjective test results. The correlation between the proposed quality metric and the subjective test results is shown to be stronger than standard quality metrics, such as Video Quality Metric (VQM).
