摘要

高效视频编码(High Efficiency Video Coding, HEVC)旨在提供比以前的视频标准显著提高的压缩性能。去块滤波器对编码块边界处的工件执行检测，并通过应用选定的滤波器对其进行衰减。本文提出了一种基于改进边界决策方法的高效去块滤波算法。可以选择预测单元或变换单元边界，根据所有8×8块的Depth, transx和PartitionSize信息过滤8×8块的所有边界。实验结果表明，在相同的性能和比特率下，该算法与HM中的DF算法相比，可以显著提高编码效率，并具有更好的并行处理能力。

An efficient deblocking filter algorithm for HEVC

The High Efficiency Video Coding (HEVC) aims to provide significantly improved compression performance in comparison with the previous video standards. The deblocking filter performs detection of the artifacts at the coded block boundaries and attenuates them by applying a selected filter. In this paper, we proposed a novel and efficient deblocking filter algorithm baed on the improved boundary decision method. Prediction unit or transform unit boundaries can be selected to filter all boundaries of 8×8 block according to the Depth, TransformIdx and PartitionSize information from all 8×8 block. Experiment results show that the proposed algorithm can achieve significant coding efficiency improvements and better parallel processing capabilities with the same performance and bit-rate compared with the DF algorithm in HM.
