static class

HierarchyState.Type Represents the type of a hierarchy state.

Constructor Summary

HierarchyState(HierarchyCriterion hierarchyCriterion)
State representing a hierarchy constructed using the hierarchyCriterion and with the hierarchy root selected (only one ROI).

HierarchyState(int[] labels, HierarchyCriterion hierarchyCriterion)
State representing a hierarchy constructed using the hierarchyCriterion and that contains the partition derived from labels.

HierarchyState(int threshold, HierarchyCriterion hierarchyCriterion)
State representing a hierarchy constructed using the hierarchyCriterion and with a partition selected by the given threshold.

Method Summary

HierarchyCriterion	getHierarchyCriterion() Returns the criterion from with the hierarchy was derived.
int[]	getLabels() Returns a labeling function that determines the selected partition.
int	getThreshold() Returns the threshold used to select a partition from the hierarchy.
