摘要

近年来，多视点视频编码受到了广泛的关注。然而，多视点视频编码的错误恢复能力尚未得到深入的研究。本文提出了一种新的错误恢复方法来减轻传输过程中丢包的影响。使用带宽效率高的冗余编码，其中仅为位于感兴趣区域(ROI)内的选定宏块生成冗余流。采用Otsu灰色阈值法选择roi。采用联合可扩展视频模型(JSVM)编解码器实现了该系统，并在模拟Internet协议分组网络环境中对其性能进行了分析。结果表明，就PSNR和SSIM指标而言，所提出的系统提供了相当大的质量增益

Error resilience for multi-view video using redundant macroblock coding

Multi-view video coding has received a considerable amount of interest in recent years. However, error resilience for multi-view video coding has not yet been investigated in great depth. This paper presents a novel error resilience method to mitigate the effects of packet loss during transmission. Bandwidth efficient redundant coding is used, where the redundant stream is generated only for selected macroblocks that fall within a Region of Interest (ROI). Otsu's gray threshold selection method is employed for selecting ROIs. The proposed system is implemented using the Joint Scalable Video Model (JSVM) codec and its' performance is analyzed in a simulated Internet protocol packet network environment. The results show that the proposed system provides considerable quality gain, in terms of both PSNR and SSIM metrics
