public class AlgorithmThresholdDual
extends AlgorithmBase

This algorithm has two modes of operation:

1. Generates binary image based on threshold values passed in by the constructor. Inside the volume of interest: If the image intensity is greater than or equal to the threshold[0] and less than or equal to the threshold[1], the binary image is set to one. Otherwise, it is set to zero. Outside the volume of interest: The binary image is set equal to zero.

2. Inside the volume of interest: Preserves all grey scale values from threshold[0] to threshold[1] and sets all values less than the lower threshold and all values greater than the upper threshold to the fillValue supplied to this algorithm via the constructor. Outside the volume of interest: Sets all gray scale values to the fill value.
