Graph-Based Parallelization Algorithm for Deblocking Filter in H.264/AVC

Abstract

Wavefront parallelization speeds up the deblocking filter in multi-core platforms, but it has a limitation in achieving sufficient parallelism owing to data dependency among macroblocks. To overcome this limitation, we propose a novel approach of parallelizing the deblocking filter by exploiting the conditional data dependency affected by the boundary strength 1 for each macroblock edge.
