class  Cluster
 Class that represent a cluster of items to be classified as a single atomic object. More...
 
class  Evaluation
 Class to compute several measurements to evaluate the quality of a classification output. More...
 
class  Face_descriptor_to_center_of_mass_map
 Property map that constructs the center of mass of the face of a mesh on-the-fly. More...

Functions

template<typename ConcurrencyTag , typename ItemRange , typename Classifier , typename LabelIndexRange >
void classify (const ItemRange &input, const Label_set &labels, const Classifier &classifier, LabelIndexRange &output)
 runs the classification algorithm without any regularization.
 
template<typename ConcurrencyTag , typename ItemRange , typename ItemMap , typename NeighborQuery , typename Classifier , typename LabelIndexRange >
void classify_with_local_smoothing (const ItemRange &input, const ItemMap item_map, const Label_set &labels, const Classifier &classifier, const NeighborQuery &neighbor_query, LabelIndexRange &output)
 runs the classification algorithm with a local smoothing.
 
template<typename ConcurrencyTag , typename ItemRange , typename ItemMap , typename NeighborQuery , typename Classifier , typename LabelIndexRange >
void classify_with_graphcut (const ItemRange &input, const ItemMap item_map, const Label_set &labels, const Classifier &classifier, const NeighborQuery &neighbor_query, const float strength, const std::size_t min_number_of_subdivisions, LabelIndexRange &output)
 runs the classification algorithm with a global regularization based on a graph cut.
 
template<typename ItemRange , typename ItemMap , typename IndexMap >
std::size_t create_clusters_from_indices (const ItemRange &range, ItemMap item_map, IndexMap index_map, std::vector< Cluster< ItemRange, ItemMap > > &clusters)
 Given a set of cluster indices, segments the input range into Cluster objects.
 
template<typename FeatureType >
FeatureType * feature_cast (Feature_handle fh)
 casts a feature handle to a specialized feature pointer.
