摘要 在无线网络环境下的视频通信过程中,错误隐蔽是一种提高解码图像质量的重要手段。提出了一种针对实时视频应用的自适应时域运动补偿处理方法,不仅考虑了受损视频在时间上的相关性,而且针对补偿图像中的块效应进行自适应处理,能够有效地提高解码图像质量。 Error concealment is an important method to improve image quality for wireless video communications. An adaptive temporal error concealment method is proposed for real-time video application. Specially, the previous frame is utilized to compensate the damaged area, and the block artifacts in the compensated image are processed adaptively to improve the decoded image quality.
