initializeVisualizer()

virtual void ProbabilisticSceneRecognition::SceneObjectLearner::initializeVisualizer ( boost::shared_ptr< Visualization::ProbabilisticSceneVisualization >  mSuperior )

pure virtual

Initializes the visualization mechanism.

Parameters

mSuperior

The superior visualizer coordinating the scene visualizers.

Implemented in ProbabilisticSceneRecognition::OcmSceneObjectLearner.

learn()

virtual void ProbabilisticSceneRecognition::SceneObjectLearner::learn ( std::vector< ISM::ObjectSetPtr >  pExamplesList, boost::shared_ptr< SceneModel::TreeNode >  tree  )

pure virtual

mMaxAngleDeviation

double ProbabilisticSceneRecognition::SceneObjectLearner::mMaxAngleDeviation

protected

Definition at line 129 of file SceneObjectLearner.h.

mPriori

double ProbabilisticSceneRecognition::SceneObjectLearner::mPriori

protected

The a priori probability for this scene. Will be set to an equal distribution for all scenes.

Definition at line 114 of file SceneObjectLearner.h.

mSceneObjectType

std::string ProbabilisticSceneRecognition::SceneObjectLearner::mSceneObjectType

protected

The type of the scene object. Because we don't use any instance information this is also the identity of the scene object.

mStaticBreakRatio

double ProbabilisticSceneRecognition::SceneObjectLearner::mStaticBreakRatio

protected

Parameters of heuristics used for hierarchical clustering.

Definition at line 129 of file SceneObjectLearner.h.

mTogetherRatio

double ProbabilisticSceneRecognition::SceneObjectLearner::mTogetherRatio

protected

Definition at line 129 of file SceneObjectLearner.h.

mWorkspaceVolume

double ProbabilisticSceneRecognition::SceneObjectLearner::mWorkspaceVolume

protected

The volume of the workspace the scene takes place in qubic meters.
