How to create a mask/ ROI from Json file

Hey All,
I try to run a detection model using an imageJ plugin (U-net). I have a set of segmented photos, the segmentation saved in a Json format. I’m trying to find a simple way to convert the Json into a mask, so I’ll be able to use the U-net plugin.

you’re helping will be more than appreciated.


Unfortunately as it stands, your question is a bit too vague. What was used to produced the Json file? Can you share a file here?
