Threshold an image.
Set image values to a user-specified outside value if they are below, above, or between simple threshold values.
ThresholdAbove: The values greater than or equal to the threshold value are set to OutsideValue.
ThresholdBelow: The values less than or equal to the threshold value are set to OutsideValue.
ThresholdOutside: The values outside the range Lower-Upper are set to OutsideValue.
Although all image types are supported on input, only signed types are produced.
Most frequently used for these scenarios:
- Use Case 1: threshold a CT to recover bone structures
- Use Case 2: create a mask volume to limit processing to a region of a brain (for example, a tumor showing up as higher intensity)
Panels and their use
- The Editor module also has a threshold function
