Other AbstractThe invention relates to a spatial-spectral associated prediction-based hyperspectral image lossless compression method, which comprises the following steps: conducting band combination to input hyperspectral images according to the magnitude of a spectrum correlation coefficient; selecting corresponding prediction algorithms according to different band combinations to eliminate correlation and to obtain a difference image; and conducting RICE entropy coding to the difference image to obtain a compressed code stream, storing or transmitting the compressed code stream and realizing reversible decoding locally or at other places. By adopting the method, the invention has the advantages that the spatial-spectral redundancy of the entire image can be effectively reduced, the calculated amountfor coding is reduced, no information is lost in the entire coding process, the lossless compression is realized, the lossless compression ratio of the hyperspectral image is improved, the storage resource required for image storage is reduced, the transmission bandwidth burden is reduced, the coding complexity is low, the hardware realization and the real-time transmission are facilitated and the error resilience is good.
