[Help-gsl] k-level wavelet decomposition

[Razmig K]

Hello,

the GSL reference manual states on page 321 that the total number of
levels for 1D wavelet transform is log2(n), I assume that this also
holds for 2D wavelet transform since no explicit information is given
in the relevant section of the reference manual.
Now, I would like to achieve k-level 2D wavelet decomposition of
square grayscale images into LL, LH, HL and HH bands for further usage
of LL band information.
Any hints on how to do this with GSL wavelet tools?

Thanks,
~Razmig
