Help with marking ROI's in ImageJ

Hello imageJ community

I am completely new at using ImageJ and I haven’t been able to find anything about my particular problem. I am working with image segmentation.

I have a large set of CT images in which I have to mark and analyze specific ROI’s. The images are transformed into binary images where the ROI’s are white clusters and the background is black. The position of the ROI’s differ however, so I have to mark each ROI manually in every image manually.
Is there a way to mark the ROI’s automatically in all images?

Best regards :slight_smile:

@lipa Can you share an example binary image with us? Too - indicate what you need to segment - perhaps in another image that is annotated…
