Abstract
A system is presented for compression of hyperspectral imagery. Specifically, DPCM is used for spectral decorrelation, while an adaptive 2-D discrete cosine transform (DCT) ( ) coding scheme is used for spatial decorrelation. Trellis coded quantization ( ) is used to encode the transform coefficients. Side information and rate allocation strategies ( ) are discussed. Entropy-constrained codebooks are designed using a modified version of the generalized Lloyd algorithm
