Abstract

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