#20 Answer: Biorthogonal wavelets and lifting scheme (WD 6.10#23)

Hi Laurent,

We have written a wavelet transform library based on biorthogonal
wavelets and the lifting scheme: WAILI -- Wavelets with Integer
Lifting. The implementation of all transforms starts from the lazy
wavelet transform.

You can find more information, including some papers describing the
mathematics behind WAILI, at
