| Outline of Final Research Achievements |
We realized a technology that enables multiple viewers to observe 3D free-viewpoint video with SDTV image quality via the network arbitrarily choosing their viewpoints.
As the free-viewpoint video generation technology suitable for higher image quality, we made a systematic comparison between the player-billboard method which we originally have developed and the method based on 3D shape reconstruction. We confirmed the player-billboard method is superior to the 3D reconstruction based method for generating high quality video. We have examined the feasibility of our technology to utilize in the live video delivery via network and in the playback type content production. We also developed Mixed-Reality presentation methods such as an immersive display with player's point of view.
