• High Threshold / Low Threshold - When Operator is set to BINARIZE, any value outside this range in the pre-processed input is converted to 0; any value inside this range is converted to 1. When Operator is set to PASSRANGE, any value below Low Threshold is converted to the value of the Low Threshold. Any value above High Threshold is converted to the High Threshold. Values in between the two thresholds are unchanged. Both thresholds should be an integer ranging from 0 to 255.
