Abstract
Efficient multi-view coding requires coding algorithms that exploit temporal, as well as inter-view dependencies between adjacent cameras. Based on a spatiotemporal analysis on the multi-view data set, we present a coding scheme utilizing an H.264/MPEG4-AVC codec. To handle the specific requirements of multi-view datasets, namely temporal and inter-view correlation, two main features of the coder are used: hierarchical B pictures for temporal dependencies and an adapted prediction scheme to exploit inter-view dependencies. Both features are set up in the H.264/MPEG4-AVC configuration file, such that coding and decoding is purely based on standardized software. Additionally, picture reordering before coding to optimize coding efficiency and inverse reordering after decoding to obtain individual views are applied. Finally, coding results are shown for the proposed multi-view coder and compared to simulcast anchor and simulcast hierarchical B picture coding.
