1 Date of download: 5/29/2016 Copyright © 2016 SPIE. All rights reserved. Three-dimensional wavelet transform structures. The number on the front upper left corner for each subband indicates the initialization order of the list LINk for the 3-D EZBC algorithm. (a) 3-D dyadic wavelet transform (two levels). (b) 3-D wavelet packet transform (two spectral levels, 1-D DWT, plus two spatial levels, 2-D DWT). (c) Xiong et al. ’s 3-D integer wavelet packet transform (two spectral levels, 1-D WPT, plus two spatial levels, 2-D DWT).
