So, it's like multispectral classification even if it can be processed
theoretically with one band. We could not recongize this function under this
name.

Hi All,
I'm looking for a function that create an image segmentation.
Is there a function in the GDAL collection that permit to do that?
Giacomo,
No, I don't believe there is.
By segmentation do you mean single band reclassification (ie. values
0-10 map to 1, values 20-35 map to 2, etc)? Or are you thinking of
multispectral classification? Or perhaps something else?
Image segmentation is the spatial partitioning of an image typically.
In any event, there is nothing in GDAL itself to do any of these.
In GRASS you can find it:
