Pseudo code for 3D-DWT.

(1) Load 3D data set into V

(2) [x y z] = size(V)

(3) for   𝑘=1 to 𝑧   do

(4)  apply 2D-DWT for each plane in Z-axis

(5) end for

(6) for   𝑖=1 to 𝑥 do

(7)  for   𝑗=1 to 𝑦   do

(7)   apply 1D-DWT for all vectors corresponding to each

    pixel in XY plane

(10)    end for
