Intra Frame Flicker Reduction for Parallelized HEVC Encoding

The existing intra flicker artifact reduction approaches, targeting at one of the major artifacts in current video encoding techniques, are not compatible with the distributed encoding structure, which is increasingly important in modern computing systems. To settle this problem, we propose a flicker reduction approach, which is effective, standard compliant, and especially suitable for parallel and distributed systems. Experimental results show that the proposed approach can reduce the flicker artifact by up to 60% on x265 and 14% on HM.
