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