Best wavelet packet bases in a rate-distortion sense

Electronic experts have developed a new method for signal compression by decomposing wavelet packets on the model of an adaptive tree structure. Decomposition of a direct signal takes place by using wavelet packets as the basis of a given wavelet kernel to discover the best wavelet packet model. A layout that includes both rate and distortion is worked on to prune the tree, which denotes the entire collection of permissible wavelet packet basis, to arrive at the most suitable basis subtree which would reduce the coding bit rate for better target quality.
