| 摘 要： | 具有独特编码结构的3D视频在不可靠信道上传输时遭遇丢包后极易造成错误传播,因此研究基于3D视频的错误隐藏技术十分必要。而且,压缩后传输的3D视频数据量仍然较大,这对解码器的解码速度提出了很高的要求。如何在解码端加速进行错误隐藏是研究重点,通过快速定位静止宏块的方法加速错误隐藏速度。实验结果表明该算法在保证不降低视频的主、客观质量的同时,能有效地降低错误隐藏算法的复杂度。

| Abstract: | The 3D video has a unique coding structure,it can lead to worse damage than traditional 2D video when video transport in unreliable channel.So it is very necessary to study error control technology based on 3D video.The compressed 3D video date is still large which makes a very high demand for the decoder decoding speed.How to speed up the decoder error concealment is the focus of this study,this paper speed error concealment up by quick locating static Macroblock.Experimental results show that the algorithm can effectively reduce the complexity of error concealment algorithms and not reduce the video quality at the same time. |
