New visual coding exploration in MPEG: Super-MultiView and free navigation in free viewpoint TV

摘要

ISO/IEC MPEG and ITU-T VCEG have recently jointly issueduda new multiview video compression standard, called 3D-HEVC,udwhich 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 theseudtargets are within reach, with at least 6% bitrate gains over 3DHEVCudtechnology.
