Title
Synthesized View Distortion Based 3D Video Coding for Extrapolation and Interpolation of Views
Abstract
In 3D video coding, the Multi-View Video plus Depth (MVD) representation format enables the interpolation of virtual intermediate views in between the original recorded camera views, as well as the extrapolation of views outside this range using view synthesis algorithms. For this, MVD includes depth maps as additional information to be transmitted. The performance of the associated depth data coding can be improved by considering the distortion of synthesized views in the rate-distortion optimization of the encoder. Therefore, this paper evaluates coding gains achieved with encoder optimization with respect to virtual view positions. The impact of the number and the positions of virtual views used as reference in the encoder side optimization process on the quality of the synthesized views is analyzed. Coding results for view interpolation and view extrapolation are provided. Moreover, the encoder-side complexity with respect to the number of reference views is discussed.
