Abstract

This paper compares the objective and subjective performance of direct and hierarchical subband decomposition schemes for image coding. It is observed that the hierarchical subband schemes outperform the direct structures in image coding. It is also shown that the dyadic tree subband codec outperforms the full-tree case for the image coding experiments performed in this study.
