摘要
在已有去块滤波算法的基础上,根据人类视觉系统的特点,提出了一种改进的、以块边界为单位的后处理去块滤波算法。该算法能以较少的硬件资源得到更好的视觉效果。文中还给出了对应的硬件实现结构,在使用较少的存储单元情况下,仿真结果仍然可以达到H.264视频实时处理的频率要求。
An improved post-processing deblocking filter algorithm with the unit of block boundary is presented based on the feature of human visual system （HVS）. The result shows that it can earn better visual effect with less hardware sources. Besides, the corresponding hardware architecture with less memory and high performance is also presented, which can meet the speed of real-time H.264 decoding in the simulation.
