Abstract :
The concept of progressive optimization is proposed for the design of hierarchical subband transforms. The time and frequency properties of the product filters in subband trees are discussed and evaluated. It is shown that the performance improvements in image coding are possible by using different PR-QMF banks at different nodes of a subband tree
