I'm trying to check the 2D wavelet transform for floating point image buffers. I want to use the Biorthogonal 9/7 filters (of lengths 9 & 7). I've read the manual and the 2D wavelet example. I've sucessfully implemented the Daubechies 2 filter similat to the example. When I triedtheBiorthogonal 9/7 filterswith several anchor choises, I failed to reconstruct the image.I have 1 open question - how to determine the anchor values for both forward and inverse transform? obviously this is not an arbitrary choise as most choices fails to reconstruct (or approximatly reconstruct) the original image.
