H.264中的去块滤波的分析及优化

Analysis and Optimization of Adaptive Debloking Filter in H.264

本文介绍了新一代视频编码压缩标准H.264中的去块滤波器的滤波过程,对滤波的复杂度进行了详细分析,并提出了一种新的多档次的去块滤波的方法。试验证明H.264中的去块滤波器在主观及客观图像质量上都获得了提高,新提出的滤波方法较好的解决了图像质量和滤波消耗时间上的平衡性问题。

This paper describes the adaptive deblocking filter used in the H.264/AVC video coding standard. The complexity of the deblocking filter is analyzed in detail. We also introduce a new multi-level deblocking filter. Experimental results show that the adaptive deblocking filter in H.264 can improve both subjective and objective image quality. And the balance of image quality and computation time also gets resolved by the new approach.
