An effective method of deblocking filter for H.264/AVC

In order to reduce the blocking artifacts in the video frames, the latest video standard H.264/AVC introduces an in-loop deblocking filter technique. The main drawback of the filter is its high computational complexity. Among the process of this filter, the most computational resource consumed is the determination of Bs, so in this paper we propose an optimized pre-judging Bs method to reduce the computational complexity. The computer simulation results indicate that our proposed algorithm can decrease 69.4% ~76.9% computing time compared to the JM filter algorithm, and the PSNR of ours is the same to that of JM.
