| Abstract: | The correlation of HRIS spectral image sequence was analyzed in this paper. A lossless compression algorithm based on D 2PCM coder, which reduced the spectral and spatial correlation, has been developed. The proposed method depressed the image redundancy sufficiently, and increased compression ratio and efficiency. The results of experiments prove it practicable and fast. |
