Low Bandwidth Hybrid Color Compensation for Multiview View Synthesis

Multiview video applications are getting emerging in the recent years by its 3D and free-view-point perception functionalities. To support smooth viewpoint switching, virtual view synthesis is required. However, the color information between each view is different due to the difference between multiview cameras. Further, the complexity and the corresponding bandwidth grow up dramatically with number of views. In order to make the real-time multiview application practical, a low bandwidth hybrid color compensation scheme is proposed in this paper. By the proposed motion propagation scheme reduces the frame-level processing times from each frame to once every six GOP. Finally, the proposed adaptive average assignment and the regularized access pattern reduce the bandwidth requirement at one frame by 45.4% with only 0.05dB quality drop.
