Decoder Side Multiplane Images using Geometry Assistance SEI for MPEG Immersive Video

Résumé

The MPEG Immersive Video (MIV) standard enables a novel technology denoted as decoder side depth estimation (DSDE) by introducing a dedicated Geometry Absent profile. In DSDE only texture information is coded and the corresponding geometry is reconstructed on the decoder side. MIV further enables the coding of side-information useful to the geometry reconstruction, denoted as Geometry Assistance SEI message. An emerging format for immersive video are Multiplane Images, which is investigated for feasibility in coding systems due to their promising rendering quality with complex sequences. In this work, we show that MIV can be used to construct block-based Multiplane Images on the decoder-side and to enhance the view synthesis performance utilizing the Geometry Assistance SEI. In a complexity-aware setting using only 32 planes, up to 6 dB of quality improvement is achieved compared to the reference.
