Abstract EN
The data size of hyperspectral image is too large for storage and transmission, and it has become a bottleneck restricting its applications.
So it is necessary to study a high efficiency compression method for hyperspectral image.
Prediction encoding is easy to realize and has been studied widely in the hyperspectral image compression field.
Fractal coding has the advantages of high compression ratio, resolution independence, and a fast decoding speed, but its application in the hyperspectral image compression field is not popular.
In this paper, we propose a novel algorithm for hyperspectral image compression based on hybrid prediction and fractal.
Intraband prediction is implemented to the first band and all the remaining bands are encoded by modified fractal coding algorithm.
The proposed algorithm can effectively exploit the spectral correlation in hyperspectral image, since each range block is approximated by the domain block in the adjacent band, which is of the same size as the range block.
Experimental results indicate that the proposed algorithm provides very promising performance at low bitrate.
Compared to other algorithms, the encoding complexity is lower, the decoding quality has a great enhancement, and the PSNR can be increased by about 5 dB to 10 dB.
