## Detailed Description

Options object for hierarchical clustering.

#include <vigra/hierarchical_clustering.hxx>
Namespace: vigra

This class allows to set various parameters of hierarchicalClustering(). See there for usage examples.

Examples:
  graph_agglomerative_clustering.cxx.

## Member Function Documentation

ClusteringOptions& minRegionCount | ( | size_t | count | ) |

Stop merging when the number of clusters reaches this threshold.

Default: 1 (don't stop early)

ClusteringOptions& maxMergeDistance | ( | double | val | ) |

Stop merging when the weight of the cheapest edge exceeds this threshold.

Default: infinity (don't stop early)

ClusteringOptions& nodeFeatureImportance | ( | double | val | ) |

Importance of node features relative to edge weights.

Must be between 0 and 1, with 0 meaning that node features are ignored, and 1 meaning that edge weights are ignored.

Default: 0.5 (equal importance)

ClusteringOptions& sizeImportance | ( | double | val | ) |

Importance of node size.

Must be between 0 and 1, with 0 meaning that size is ignored, and 1 meaning that the algorithm prefers to keep cluster sizes balanced.

Default: 1.0 (prefer like-sized clusters)

ClusteringOptions& nodeFeatureMetric | ( | metrics::MetricType | metric | ) |

Metric to be used when transforming node features into cluster distances.

The cluster (= node) distance is the respective norm of the difference vector between the corresponding node feature vectors.

Default: metrics::ManhattanMetric (L1-norm of the feature difference)

ClusteringOptions& verbose | ( | bool | val = `true` | ) |

Display progress information.

Default: false
