Boundary handling for video-based light field coding with a new hybrid scan order

摘要

In video-based light field coding, sub-aperture images (SAIs) are ordered to form a pseudo video sequence, and thesequence is encoded by a video compression algorithm, for example, by HEVC. When the size of SAI is not divisible bythe minimum size of coding tree unit, proper boundary handling method is required. This paper investigates severalboundary handling methods. To maintain high quality of the central SAIs, we combine rotation and u scans to have anew hybrid scan order. Random access configuration is used instead of low-delay one for better coding efficiency. Theproposed methods are evaluated with the latest coding tool.
