An effective compression technique for hyperspectral images has become one of the focuses in the field of space hyperspectral remote sensing. The lossless compression technique of hyperspeetral images based on distributed source coding （DSC） is studied in this paper. First, the theoretical foundation, realizable manner of DSC and its advantages in lossless compression of hyperspectral images are introduced. Then the research progress of lossless compression of hyperspectral images based on DSC is summarized, a distributed lossless compression algorithm of hyperspeetral images based on muhiband prediction is proposed. Experimental results show that the proposed algorithm has low encoding complexity, its compression performance is also better than that of the existing distributed compression algorithms. Finally, the problems which need further research on DSC application in hyperspectral images compression are pointed out.
