Hi devs,
I just discovered this [0], I think it could be really useful this
functionality in GRASS too, what do you think?
The code is LGPL so it could be ported "easily" in GRASS.

IIUC, it's a new technique for image fusion ? As of now, we have
i.pansharpen in core which offers very basic fusion techniques and
Nikos' i.fusion.hpf in addons. New techniques would certainly be welcome.
A while ago, I was looking at Bayesian fusion methods, notably R-FUSE [1], for which Matlab code is available [2], but haven't had the time to go further. That might be another method that would be great to implement.
Maybe also something to keep in mind for next GSoC ?

This sounds like a great idea, please don't let it fade out, it's always a
good time to collect the ideas into the ideas page
Thanks

Certainly a valued addition for GRASS and the community.

There is also this one http://www.freepatentsonline.com/8737733.html.
Not exactly new. Yet, I fear it cannot be freely used (as in cost-free).
If anyone could confirm.

From the documentation:
“The method is quite computationally intensive. Please use a small test region of interest first, and only then expand according to your needs / available computing power.”
This should be tested first to decide if it should be included in GRASS GIS. People tend to throw huge datasets into GRASS and expect that it works.
