Hi,
It depends on the what function you are trying to achieve i guess. There are different types of ROI you can select. Try reading the ROI descriptor help. But some VIs will take only rectangle co-ordinates as ROI.
In some VIs you can pass the Mask image which will define which area to look for. Reading the through the VIs help, will give you some idea.
Thanks,
logic
