Outline of Apply Threshold


I’m using ApplyThreshold to work out the area occupied by mucus in an image. I’d like to put an overlay onto the original image to show where’s thresholded. If I were using IndentfyxxxxObjects I’d be able to do this using OverlayOutlines. Do you know how I can do this for ApplyThreshold?



Hi Nick,

The best workaround I can think of for this is to go ahead and identify the region as an object and turn on the outlines. In IdentifyPrimaryObjects, to replicate the results of ApplyThreshold, you would want to

  • Disable the size exclusion and image border exclusion settings.
  • Use the same thresholding method as in ApplyThreshold.
  • Set declumping to None.



Thank you for the suggestion - that works.
