A data processing system augments compression of non-zero values of significant coefficients by coding (1410, 1412) en- tries of a significance map independently of coding the values of significant non-zero coefficients. A dedicated symbol represents a zerotret structure encompassing a related association of insignificant coefficients within the tree structure, thereby compactly representing each tree of insignificant coefficients. The zerotree symbol represents that neither a root coefficient of the zerotree structure nor any descendant of the root coefficient has a magnitude greater than a given reference level. The zerotree structure is disclosed in the content of a pyramid-type image subband processor (1408) together with successive refinement quantization and entropy coding (1418) to facilitate data compression.
