Field Summary

static HierarchyCriterion	AREA Criterion of synchronous flooding, used to rank regions according to their area.
static HierarchyCriterion	DEPTH Criterion of synchronous flooding, used to rank regions according to their contrast.
static HierarchyCriterion	MEAN_VALUE Criterion to build hierarchies merging adjacent regions by the similarity of the mean values of their pixels.
static HierarchyCriterion	MERGING_LEVEL Criterion of uniform flooding.
static HierarchyCriterion	VOLUME Criterion of synchronous flooding, used to rank regions according to their contrast and area.

Method Summary

AbstractMetric	getMetricObject() Returns a new instance of the AbstractMetric associated with this HierarchyCriterion.
java.lang.String	getName() Returns the name of this HierarchyCriterion.
boolean	isFloodingCriterion() Returns if this HierarchyCriterion is a flooding criterion or a generic criterion.
static boolean	isValid(java.lang.String criterionName) Returns if there is a valid HierarchyCriterion for the given criterionName.
static HierarchyCriterion	valueOf(java.lang.String criterionName) Returns the HierarchyCriterion associated with the name criterionName.
static java.util.Collection<HierarchyCriterion>	values() Returns a Collection with all the existing HierarchyCriterion.
