Dear Slicer Community,
I have been using the Segment Editor to segment an image that takes on 3 discrete Hounsfield Units (0,1,2). The images contain 2 cells, cell1 is in HU=1, cell2 is in HU=2. The background is HU=0.
I must not be using the Thresholding tool properly, because even if I set the intensity range correctly to get cell2 but not cell1 (thresholding with HU>1.88) it will still segment both cells:
Alternatively, if I set the intensity range for threshold to be between 0.9 and 1.1 to segment out cell1 (and not cell2), it includes all the background!
What am I doing wrong? Any help would be really appreciated!!
