Abstract

In this paper, we study the joint source-channel coding of object-based video, and propose a data hiding scheme that improves the video error resilience by adaptively embedding the shape and motion information in the texture data. Within a rate-distortion theoretical framework, the source coding, channel coding, data embedding, and decoder error concealment are jointly optimized based on the knowledge of transmission channel conditions. The problem is solved using Lagrangian relaxation and dynamic programming. Experimental results indicate that the proposed hybrid source-channel coding scheme significantly outperforms methods without data hiding or unequal error protection

一种基于对象的无线视频通信混合源信道编码方案

本文研究了基于对象的视频的源信道联合编码，提出了一种数据隐藏方案，通过自适应地在纹理数据中嵌入形状和运动信息，提高视频的容错性。在速率失真理论框架下，基于对传输信道条件的了解，对信源编码、信道编码、数据嵌入和解码器错误隐藏进行了联合优化。利用拉格朗日松弛法和动态规划方法解决了该问题。实验结果表明，所提出的混合源信道编码方案明显优于无数据隐藏和非等错保护的编码方案
