Question about haralick module and in particular the "normalisation" aspect
Description
I become aware with different processing on different S2 images that the values obtained within a same image are not independent. Indeed when there is snow or cloud,… on a part of the image, it seems that a bias appears for the values on the all image.
After a discussion bu e-mails with Julien Michel, he assumes that it is perhaps a bug.
Could you please tell me more about the way of the computation of haralick feature computation ? And perhaps (if the behavior of the module is normal) give me some advices of pre and/or post processing in order to obtain comparable values over time on my area of interest whatever the spectral content of the other parts of the image.
Thanks a lot for your help Aline Déprez
