CGAL::Classification::Feature::Cluster_variance_of_feature Class Reference

#include <CGAL/Classification/Feature/Cluster_variance_of_feature.h>

Inherits from

CGAL::Classification::Feature_base.

Definition

Feature that computes the variance values of an itemwise feature over the respective items of clusters.

Its default name is "variance_" + the name of the itemwise feature.

Cluster_variance_of_feature()

template<typename ClusterRange >

CGAL::Classification::Feature::Cluster_variance_of_feature::Cluster_variance_of_feature	(	ClusterRange &	clusters,
		Feature_handle	itemwise_feature,
		Feature_handle	mean_feature

Constructs the feature.

Template Parameters

ClusterRange

model of ConstRange. Its iterator type is RandomAccessIterator and its value type is the key type of Cluster.

Parameters

clusters	input range.
itemwise_feature	feature that takes values on the range of items from which clusters is a subset.
mean_feature	Cluster_mean_of_feature computed on itemwise_feature.
