CGAL 5.6 - Classification
|
Data structures specialized to classify clusters.
Classes | |

| Feature that computes the mean values of an itemwise feature over the respective items of clusters. More... | |
| class | CGAL::Classification::Feature::Cluster_size |
| Feature that returns the size of each cluster. More... | |
| class | CGAL::Classification::Feature::Cluster_variance_of_feature |
| Feature that computes the variance values of an itemwise feature over the respective items of clusters. More... | |
| class | CGAL::Classification::Feature::Cluster_vertical_extent |

#include <CGAL/Classification/Cluster.h>
Given a set of cluster indices, segments the input range into Cluster objects.
All items whose index value idx (accessed through index_map) is the same are stored in the same cluster at position idx in the clusters vector.
| ItemRange | model of ConstRange. Its iterator type is RandomAccessIterator. Its value type depends on the data that is classified (for example, CGAL::Point_3 or CGAL::Triangle_3). |
| ItemMap | model of ReadablePropertyMap whose key type is the value type of the iterator of ItemRange and value type is the type of item to classify (for example, CGAL::Point_3). |
| IndexMap | is a model of ReadablePropertyMap with value type int. |
| range | input range. |
| item_map | property map to access the input items. |
| index_map | property map that associates the index of an item in the input range to the index of a cluster (-1 if item is not assigned to a cluster). |
| clusters | container where generated Cluster objects are stored. |
