As Dan mentioned, you could use/extend his GIFT framework for any DWT's (discrete wavelet transforms)<br><br>On 2/4/07, <b class="gmail_sendername">Dan Mueller</b> <<a href="mailto:d.mueller@qut.edu.au">d.mueller@qut.edu.au

I have provided an implementation of QMF (quadrature mirror filter)
wavelet decomposition and recomposition in ITK (for the application of
image fusion). I'm not familiar with the particulars of wavelet <i>packets</i>
but perhaps the QMF filter can get you started:</font></small></div></blockquote><div><br>WPT goes one step further than DWT. Unlike DWT which recursively decomposes the low pass subband, the WPT, at every level, not only decomposes the low pass subband, but also the detail subbands.
