Algorithm 6. Pseudocode for the decompressor part of the proposed near-lossless compression.

Inputs: vecSeed, vecUnary Output: $x$ // reconstructed hyperspectral data Initialization: $index \leftarrow$ the index value obtained by interpreting the next unary code in vecUnary For all $index$ Do         $m\leftarrow$ the number bits to be read from vecSeed based on index value (Table 4).         $order \leftarrow$$\mathrm{get} \mathrm{the} \mathrm{next} m$ bits from vecSeed.         $seed\leftarrow$ get the seed value given the index (Table A1).         $\cos \theta \leftarrow$ $\mathrm{given} \mathrm{the} \mathrm{index} \mathrm{value} (\mathrm{that} \mathrm{corresponds} \mathrm{to} \sin \theta$ value), retrieve the cosine value from the lookup table.         $\sin \theta \leftarrow index/{10}^2$         $M\leftarrow seed/(1+\sin \theta )$         $s\leftarrow \cos \theta \times M$         $x\leftarrow s\times s$ End Do
