Abstract(s)
The technologies which allow an immersive user experience in 3D environments are rapidly evolving and new services have emerged in various fields of application. Most of these services require the use of 3D video, combined with appropriate display systems. As a consequence, research and development in 3D video continues attracting sustained interest. While stereoscopic viewing is already widely spread, namely in TV and gaming, new displays and applications, such as FTV (Free viewpoint TV), require the use of a larger number of views. Hence, the multiview video format was considered, which uses N views, corresponding to the images captured by N cameras (either real or virtual), with a controlled spatial arrangement. In order to avoid a linear escalation of the bitrate, associated with the use of multiple views, video-plus-depth formats have been proposed. A small number of texture and depth video sequences are used to synthesize intermediate texture views at a different space position, through a depth-image-based rendering (DIBR) technique. This technology allows the use of advanced stereoscopic display processing and to improve support for high-quality autostereoscopic multiview displays. In order to provide a true 3D content and fatigue-free 3D visualization, holoscopic imaging has been introduced as an acquisition and display solution. However, efficient coding schemes for this particular type of content are needed to enable proper storage and delivery of the large amount of data involved in these systems, which is also addressed in this chapter.
