【摘要】 为降低视频无线传输时发生的错误对视频质量的影响,提出一种基于解码端的自适应错误隐藏算法.分析解码端错误隐藏的特点,根据受损块所处区域的运动剧烈程度,自适应地选择帧内帧间错误隐藏.实验测试结果表明,该算法对于视频错误的恢复效果有一定程度的提高.更多还原

【Abstract】 In order to diminish the impact of the errors occurred during the wireless transmission of video to its quality,an adaptive error concealment algorithm based on decoder is presented in this paper.It analyzes the characteristics of the decoder-based error concealment algorithms,selects inter and intra frame error concealment adaptively according to the movement intensity of the region the damaged blocks in.The experiment results show that this algorithm can enhance the quality of the resumed video to some extent.更多还原
