Hi all,

I am now converting my code from Python to C+OpenMP for a fusion algorithm
using multi-source remote sensing images and raingauge data.
To do that I need to decompose few levels of all sources and then recompose
chosen levels from each source together.

Can I have access to the dwt_step function to enable the multi-level/source
fusion control?

Thank you,
Yann
