I. Introduction
As 3D experiences are becoming more popular, also 3D video representation solutions associated to stereo and multiview video are evolving, recognizing that a faithful, transparent and immersive representation of our world requires more than 2D video. In the multiview video arena, there are already several coding standards, notably the Multiview Video Coding (MVC) [1] standard and the more recent MV-HEVC and 3D-HEVC (High Efficiency Video Coding) standards [2] [3]. Although significant steps forward, these standards assume a linear, horizontal arrangement of the cameras and can only efficiently support narrow baselines; baseline corresponds to the distance between cameras/views.
