Parallel intra prediction for video coding
Andrew Segall, Jie Zhao, Iomoyuki Yamamoto · 2010
In this paper, we propose an intra-prediction system that is both parallel friendly and with high coding efficiency. This is achieved by combining a novel prediction strategy that reduces serial dependencies and a novel, multi-directional and adaptive prediction system. The resulting technique is compared with state-of-the-art ITU-T H.264/MPEG-4 AVC. We observe a 2× and 8× increase in parallelism for 8×8 and 4×4 partitions, respectively, and an average rate increase of less than 0.08% for predictive coding scenarios.
