在超光谱影像压缩领域,目前还没有一个公认的标准或已成熟的压缩方法,分布式信源编码(DSC)是一种新出现的应用机制。通过论述超光谱影像压缩中DSC的概念和意义,回顾DSC的理论基础,系统地研讨了超光谱影像压缩中DSC的主要方法,最后给出了DSC应用于超光谱影像压缩的应用前景、发展现状和技术难点。

As for hyperspectral image compression, there is no standard or mature paradigm and distributed source coding (DSC) is a new scheme. In this paper, first,the concept and significance of distributed source coding in hyperspectral image compression is introduced. Second,the theoretic foundation and implementation of DSC is reviewed. Third the predominant methods of applying DSC to hyperspectral image compression are systematically discussed, and the application outlook, the current development and the technical difficulties for this technique are pointed out.
