Abstract

Hybrid wavelet packets have recently been introduced as a method which addresses the observation that the performance of a transform coding scheme may be improved by allowing the choice of QMF to be included within the analysis. The choice of appropriate QMF is not only signal dependent, but scale dependent within a given signal as well. A top-down scheme for determining a well suited hybrid wavelet packet basis is presented. This method greatly reduces the computational complexity of previous schemes allowing deeper search trees to be computed and demonstrates an associated improvement in performance.
