An integrated framework for adaptive subband image coding

A new-best basis design, in which filter banks, subband tree structure and quantizers are chosen to optimize rate-distortion performance, is presented. The new design integrated two different but complementary approaches to best-basis design. One method involves the use of fast algorithms to determine the best bases in an operational rate-distortion sense, while the other method involves the design of filter banks that optimize energy compaction for a single signal or a class of signals.
