Manual classification of Gaussian Mixture Models

Plugin : SimpleForest
Nom de classe : SF_StepManualClassifyClusters

Description

Output clusters of the step Gaussian Mixture Models with Fast Point Feature Histograms should be inspected before executing this step. Each cluster needs to be classified as good, noise or unclassified. All good clusters are merged as well as all noise clusters. Points in unclassified clusters are allocated afterwards regarding their distance to their nearest good and noise neighbors.

Paramètres

Paramètres de pré-configuration (non modifiables une fois l'étape ajoutée) :

  • Uncheck to deactivate parameterization possibilities of this step. Only recommended for beginners: Activé.

Paramètres de l'étape :

  • Compute for each unclassfied point the average distance of [k] nearest neighbors within noise and good points: 9.

  • [Classification] of the cluster number 0: Unclassified .

  • [Classification] of the cluster number 1: Unclassified .

  • [Classification] of the cluster number 2: Unclassified .

  • [Classification] of the cluster number 3: Unclassified .

  • [Classification] of the cluster number 4: Unclassified .

  • [Classification] of the cluster number 5: Unclassified .

  • [Classification] of the cluster number 6: Unclassified .

  • [Classification] of the cluster number 7: Unclassified .

  • [Classification] of the cluster number 8: Unclassified .

  • [Classification] of the cluster number 9: Unclassified .
