  • Abstract
    In this paper, a combined JPEG-2000 and spectral correlation method for hyperspectral image compression is presented. This compression scheme shows promising results. Also, various spectral decorrelation techniques are compared. The decorrelation using Karhunen-Loeve transform performs the best in terms of PSNR gain. But, since it is computationally expensive, there is no much gain over discrete cosine transform.
