Robust Multi-view Distributed Video Coding for Video Sensor Networks

针对传统无线视频传感器网络中存在的信息丢失和传感器之间需要建立通信等问题,提出一种鲁棒多视角分布式视频编码系统。通过采用改进的PRISM编码结构,在利用视角间冗余信息提高编码增益的同时将冗余用于增加编码在有损信道中传输的鲁棒性。实验结果表明,该系统在利用信息冗余获得视频压缩的基础上,对无线信道固有的数据包丢失也具有较好的鲁棒性。

To solve the problem of transmitting in the lossy channel and the requirement communication between the sensors for traditional wireless video sensor networks,a robust multi-view distributed video coding system is proposed.By using modified PRISM codec schemes,the correlation of all views to is explored to get more gains of compression.The redundancy also is used to enhance the system robust for intrinsic wireless lossy channel.Experimental results show that the proposed system accesses the compression gain,and system is also robust to wireless lossy channel.
