Where (if at all) does intensity non-uniformity (INU) correction occur?

Hi experts.

Admittedly just found out about this tool, but as I was reading both the code and the OHBM paper about it, and I can't seem to locate in the description where this is occuring.

Does this approach require INU corrections or is there a place in the code where I'm just not seeing it?

Thank you in advance.

INU is not done as part from HD-BET. In principle it should be fairly robust with respect to it, but it you find that it fails you can do a bias correction of the images before you pass them to HD-BET
