Distributed source coding (DSC) is applied to hyperspectral image compression due to its low complexity and error resilience.In the framework of typical scalar coset coding based distributed compression method (s-DSC)
it is pointed out in this paper that the infinity-norm minimization should be the best criterion for prediction
and a sub-optimal prediction method based on search for L
∞
minimum is proposed to approach the criterion.In addition
the compression scheme is extended to near-lossless compression.The experimental results show that the lossless compression bitrate of the proposed method is reduced by about 0.25bpp compared to s-DSC and the near-lossless compression outperforms JPEG-LS significantly.Owing to the advantages of low complexity
h
igh performance and error resilience
the proposed method is quite suitable for onboard compression.
