hello
I have a raster map with 1 and 0 categories.
Is there any way to determine a region in which ratio of pixel counts of these categories is 1:1
( without using trial error method ).
kind regards

How are you defining this region? How about creating a grid of 'regions', and
computing raster stats within each grid cell.
v.mkgrid
v.what.rast
you might have to do this in two passes, and then compute the percentage. Or
there might be a way to do this with r.neighbors method=diversity
??
Cheers,
Dylan

And what about r.neighbour (on map converted to fp), and than select areas where new value is about 0.5
