| Abstract |
This paper presents a new approach for achieving bitrate and pixel rate reduction in the MPEG immersive video coding setting. We demonstrate that it is possible to avoid the transmission of some depth information in the Test Model for Immersive Video (TMIV) by estimating it at the receiver's side. Although the transmitted information in TMIV is considered as non-redundant, we show that it is possible to improve this algorithm. This method provides 3.4%, 9.0%, and 12.1% average BD-rate gain for natural content on high, medium, and low bitrate, respectively, with up to respectively 12.3%, 16.0%, and 18.4% peak reductions. Moreover, it preserves the perceptual quality as measured with MS-SSIM and VMAF metrics. Additionally, it decreases the pixel rate by 8.3% for each test sequence. |
