[WM]: Daubechies' 7/9 and 5/3 filters in MatLAB

[geruta <geruta@delfi.lt>]

Hello everyone,

We are trying to use Daubechies' 5/3 and 7/9 wavelet filters for=20
watermarking in Matlab.

We tried different coefficients for the same filters as found in=20
different sources, but no one fits. Has anyone created a working 5/3 and =

7/9 filters for Matlab's Wavelet toolbox and is willing to share them? =
:)

Or maybe someone can tell how to create working filter in Matlab, when=20
we have coefficients for 'lifting' DWT, as found in Jpeg2000 standard?
