Hi Alexandre,
Did you try to :
1- dowscale your image with averaging
and
2- rescale back without interpolation
You could get a simplified map, but I'm not sure if it is exactly what you are looking for.
Cheers,
Romain

Objet : Re: Average color map in ImageJ
Hi Mark and thanks for your answer,
Unfortunetly, is it not the result i'm looking for, maybe i have too much
colors close to each other color/pixel. I will continue to find a solution.
I taught about gaussian blur with posterisation/threshold, but for now, it
doesn't work.
I looking for this because usually, NDVI map are low rez with all those
"zone" of unhealty plant, really quick to visualise and understand.
Thanks again
Cheers from Montréal
This is the kind of image i'm playing with
