The Threshold command can be used to suppress pixel values above and/or below certain values. Data exceeding the threshold level can be either set to zero, or to the threshold value.
Availability of this feature depends on Product Level.
The Maximum Threshold can be turned on/off using the Enable check box. If Zero is on, values above the threshold level are set to zero. If Zero is off, values above the threshold level are set to the threshold level.
The Minimum Threshold can be turned on/off using the Enable check box. If Zero is on, values below the threshold level are set to zero. If Zero is off, values below the threshold level are set to the threshold level.
