Method and system for processing multiview videos for view synthesis using side information
First Claim
1. A method for processing a plurality of multiview videos of a scene, in which each video is acquired by a corresponding camera arranged at a particular pose, and in which a view of each camera overlaps with the view of at least one other camera, comprising the steps of:
- obtaining side information for synthesizing a particular view of the multiview video;
synthesizing a synthesized multiview video from the plurality of multiview videos and the side information;
maintaining a reference picture list for each current frame of each of the plurality of multiview videos, the reference picture indexing temporal reference pictures and spatial reference pictures of the plurality of acquired multiview videos and the synthesized reference pictures of the synthesized multiview video; and
predicting each current frame of the plurality of multiview videos according to reference pictures indexed by the associated reference picture list.

Abstract
A method processes a multiview videos of a scene, in which each video is acquired by a corresponding camera arranged at a particular pose, and in which a view of each camera overlaps with the view of at least one other camera. Side information for synthesizing a particular view of the multiview video is obtained in either an encoder or decoder. A synthesized multiview video is synthesized from the of multiview videos and the side information. A reference picture list is maintained for each current frame of each of the multiview videos, the reference picture indexes temporal reference pictures and spatial reference pictures of the acquired multiview videos and the synthesized reference pictures of the synthesized multiview video. Each current frame of the multiview videos is predicted according to reference pictures indexed by the associated reference picture list.
