New visual coding exploration in MPEG: Super-MultiView and free navigation in free viewpoint TV
ISO/IEC MPEG and ITU-T VCEG have recently jointly issued
a new multiview video compression standard, called 3D-HEVC,
which reaches unpreceded compression performances for linear,dense camera arrangements. In view of supporting future highquality,auto-stereoscopic 3D displays and Free Navigation virtual/augmented reality applications with sparse, arbitrarily arranged camera setups, innovative depth estimation and virtual view synthesis techniques with global optimizations over all camera views should be developed. Preliminary studies in response to the MPEG-FTV (Free viewpoint TV) Call for Evidence suggest these
targets are within reach, with at least 6% bitrate gains over 3DHEVC
technology
Omnidirectional Free Viewpoint Video using Panoramic Light Fields
In this paper, we describe a system to create an omnidirectional free viewpoint experience using only a small number of input cameras. The input cameras are placed on a circle and we create a large number of novel virtual viewpoints on that circle. Next, we choose a position within that circle and compute the omnidirectional image that is visible from that position by considering the collection of virtual images as a light field. The corresponding pixels in the virtual images are selected by tracing rays from the desired viewing position. Changing your position inside the circle, results in an adapted view-dependent rendering. This creates a free viewpoint 3D VR experience. We demonstrate our method using the game engine Unity combined with the Oculus Rift
