Wavelet Packets for Compression and De-Noising

In the wavelet packet framework, compression and de-noising ideas are identical to those developed in the wavelet framework. The only new feature is a more complete analysis that provides increased flexibility. A single decomposition using wavelet packets generates a large number of bases. You can then look for the best representation with respect to a design objective, using the function besttree with an entropy function. For more details, see Using Wavelet Packets.
