[GRASS-user] new addon: i.variance

[Moritz Lennert]

Hi all,

FYI, I uploaded a simple new addon, i.variance [1], which calculates 
local variance in an image for successively degraded resolution in order 
to detect whether there are certain scales corresponding to specific, 
well-represented objects in that image. It is based on [2].

Enjoy !

Moritz
