Gaussian Mixture Models with Fast Point Feature Histograms
Plugin : SimpleForestNom de classe : SF_StepGnnFpfh
Description
For an input cloud the fast point feature histogram is computed for a given range. Gassian mixture model classification is performed to create 10 output clusters.
Paramètres
Paramètres de pré-configuration (non modifiables une fois l'étape ajoutée) :
[Only one input cloud allowed otherwise no manual classification is possible].
[Crash of this step under Linux was observed].
Normals used of FPFH are computed with [range] / 2.
The cloud is downscaled before all computations with [range] / 6. Later classification is backTransformed
Please excuse potential double citation with the step related citation for the
following general citation for SimpleForest (work on updated citable resource ongoing):
A majority of implementations are based on PCL library:

- Uncheck to deactivate parameterization possibilities of this step. Only recommended for beginners: Activé.
[Only one input cloud allowed otherwise no manual classification is possible].
[Crash of this step under Linux was observed].
- Run the FPFH estimation with [range] of 0.150 (m)..
Normals used of FPFH are computed with [range] / 2.

- Choose the [number] of gaussian mixture clusters: 0.
- Downscale the 33 dimensional FPFH matrix to [dimensions]: 5.
