  • ROI statitstics in IDL without using ENVI

    From [email protected]@21:1/5 to All on Fri Jan 5 07:50:46 2018
    Hi Group, very new to IDL programming! I have an ROI found & defined grammatically (stored in an IDLanROI object) and I need to extract the minimum and median grayscale value from a couple of grayscale images using this ROI. What is the best way to go
    about doing this in IDL? I don't have access to ENVI unfortunately! I have tried using a binary mask of the ROI but this causes problems with stats such as the median or minimum value as there are lots of zeros about!
