The significance of the zerotree hypothesis and its importance for the coding efficiency of zerotree-based wavelet image coding schemes is discussed. We apply specific coefficient permutations within the JPEG2000 and SPIHT coding pipelines which allow to control the amount of inter and intra subband correlations present in the visual data to be compressed. Results document and emphasize the importance of the zerotree hypothesis for image coding and suggest that it has a high likelihood of being correct
