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) (22) coding scheme is used for spatial decorrelation. Trellis coded quantization (23) is used to encode the transform coefficients. Side information and rate allocation strategies (36) are discussed. Entropy-constrained codebooks are designed using a modified version of the generalized Lloyd algorithm
