Randomized SVD Methods in Hyperspectral Imaging

Algorithm 4

rSVD decoder.

Input: {𝐵_𝑗,𝑄_𝑗,𝑟_𝑗̂,𝑗=1,…,𝐽}.

Output: Reconstructed matrix 𝐴.

For   𝑗=1∶𝐽  do

 (1)  Decode 𝑟_𝑗 from 𝑟_𝑗̂ with a parallel floating point decoding algorithm.

 (2)  𝐴_𝑗=𝑄_𝑗𝐵_𝑗+𝑟_𝑗.

 (3)  𝑗=𝑗+1.

end

Group all {𝐴_𝑗,𝑗=1,…,𝐽} together in 𝐴.
