Paper Abstract

This paper deals with 3DTV, more especially with 3D content transmission using disparity-based format. In 3DTV, the problem of measuring the stereoscopic quality of a 3D content remains open. Depth signal degradations due to 3DTV transmission will induce new types of artifacts in the final rendered views. Whereas we have some experience regarding the issue of texture coding, the issue of depth coding consequences is rather unknown. In this paper we focus on that particular issue. For that purpose we considered LDV contents (Layered Depth Video) and performed various encoding of their depth information - i.e. depth maps plus depth occlusions layers - using MPEG-4 Part 10 AVC/H.264 MVC. We investigate the impact of depth coding artifacts on the quality of the final views. To this end, we compute the correlation between depth coding errors with the quality of the synthesized views. The criteria used for synthesized views include MSE and structural criteria such as SSIM. The criteria used for depth maps include also a topological measure in the 3D space (the Hausdorff distance). Correlations between the two criteria sets are presented. Trends in function of quantization are also discussed.
