Towards A Multi-Terminal Video Compression Algorithm By Integrating Distributed Source Coding With Geometrical Constraints
2007
Journal of Multimedia
Preserved Fulltext
In this paper, we present a framework for multiterminal video compression (MTVC) that exploits the geometric constraints between cameras with overlapping fields of view, and then uses distributed source ...
There are two main parts of the paper -a Distributed Motion Estimation (DME) algorithm and a Distributed Source Coding (DSC) algorithm. ...
We would like to emphasize that the novelty of the proposed scheme lies in the ability to integrate distributed source coding concepts with video analysis tools that exploit the inherent geometrical constraints ...
