The coding gain due to parent-child dependencies in subband transforms is quantified. Results for both SPIHT with arithmetic coding (SPIHT-AC) and SPIHT without arithmetic coding (SPIHT-NC) are included. Results indicate that, for natural images, the parent-child coding gain is typically around 0.40 for SPIHT-NC, and 0.25 dB for SPIHT-AC.
