Three-dimensional tarp coding for the compression of hyperspectral images

An embedded wavelet-based coder for the compression of hyperspectral imagery is described. The proposed coder, three-dimensional (3-D) tarp, employs an explicit estimate of the probability of coefficient significance to drive a nonadaptive arithmetic coder, resulting in a simple implementation suited to vectorized acceleration in single-instruction-multiple-data (SIMD) hardware. The proposed 3-D tarp coder is compared to other prominent coders for the compression of hyperspectral imagery, and state-of-the-art rate-distortion performance is observed.
