摘要

在本文中，我们提出了一种新的支持分辨率递进传输的睡眠-狼(SW)视频编码。它可以实现低延迟、低分辨率的实时流，并具有较高的无损编码效率。帧内视频编码作为下采样输入视频的基础层编码器执行，并使用SW编码器作为无损存档的增强层编码器。为了提高SW无损编码效率，我们在基层和增强层之间引入了层间预测。它使用层间预测来提高运动估计(ME)的精度。仿真结果表明，该方案比JPEG2000无损编码模式具有更高的编码性能。

Slepian-Wolf video coding with resolution-progressive transmission

In this paper, we propose a new Slepian-Wolf (SW) video coding that supports resolution-progressive transmission. It can realize low-delay low-resolution real time streaming as well as high lossless coding efficiency. Intra-frame video coding is performed as the base layer coder for down-sampled input video and a SW coder is used as the enhancement layer coder for lossless archiving. In order to improve SW lossless coding efficiency, we introduce inter-layer prediction between the base layer and the enhancement layer. It uses inter-layer prediction to increase the accuracy of Motion Estimation (ME). Simulations show that the proposed scheme gives higher coding performance better than the JPEG2000 lossless mode.
