摘要 为了减小视频传输错误对解码端重建视频质量的影响,根据H.264标准的特点,提出一种基于多模式自适应叠加的时域错误隐藏算法。该算法以不同分割模式对丢失宏块进行4次隐藏,得到4个隐藏块,并计算各模式的绝对帧差和,使该值最小的2个隐藏块自适应加权叠加作为最终的替代块。仿真结果表明,与传统方法相比,该算法的错误隐藏性能得到较大提高。 In order to reduce the influence of video transmission errors on the reconstructed video quality in decoder, this paper proposes a time domain error concealment algorithm for H.264 based on multi division modes adaptive overlapping. In this algorithm, the corrupted Macro Block(MB) is concealed four times based on different division modes. The sum of absolute differences of each mode is calculated, and the weighted overlapping of the two MBs with the smallest value of sum of absolute differences is the final replacement for the corrupted MB. Simulation results show that compared with the traditional algorithms, this algorithm has better performance of concealment.
