Hi Rick,
Indeed I was talking about results from different machines being not identical. Thanks a lot for the precisions, I expected something of the kind of purpoisefully added noise but could not find that in the documentation.
I understand now that there will be some variations from one machine to the other, but what I find odd is that if I run the processing twice in a row on the same machine, I get the same images. Is it possible that the added random noise somehow tied to the machine?
Best,
Augustin
