1 * Implement more wavelet types:
2 Check the literature to find out what are commonly used types. Candidates
3 could be coiflets and symmlets.
4 ** Coefficients for coiflets and symmlets found so far are only with a
5 precision of about eight digts. This is probaly insufficient.
7 * Wavelet packet transform:
8 Should include utility functions for selecting the coefficients according
9 to "dwt-type", "best basis" or "best level".
11 * Continuous wavelet transform.
