Detailed Description

Abstract subclass of the also abstract InferenceAlgorithm class. It provides the calculations for a background scene object. This is basically a foreground scene object which is evaluated under the assumption of equal distribution.

Member Function Documentation

double ProbabilisticSceneRecognition::BackgroundInferenceAlgorithm::calculateProbabilityOfBackgroundSceneObject ( unsigned int  pNumberOfEvidence, unsigned int  pNumberOfSlots  )

protected

Calculates the probability of a single background scene object. There are multiple background scene objects, but they all have the same probability.

Parameters

pNumberOfEvidence	The number of objects to consider for the background calculation.
pNumberOfSlots	The total number of slots.

Returns

The probability of a single background scene object.

virtual void ProbabilisticSceneRecognition::BackgroundInferenceAlgorithm::doInference ( std::vector< ISM::Object >  pEvidenceList, std::ofstream &  pRuntimeLogger  )

pure virtual

Executes the inference based on the given evidence.

Parameters

pEvidenceList	A list containing all evidences.
pRuntimeLogger	A file handle for runtime logging.

Implements ProbabilisticSceneRecognition::InferenceAlgorithm.

Implemented in ProbabilisticSceneRecognition::MaximumBackgroundInferenceAlgorithm, ProbabilisticSceneRecognition::PowerSetBackgroundInferenceAlgorithm, ProbabilisticSceneRecognition::SummarizedBackgroundInferenceAlgorithm, and ProbabilisticSceneRecognition::MultipliedBackgroundInferenceAlgorithm.

virtual double ProbabilisticSceneRecognition::BackgroundInferenceAlgorithm::getProbability ( )

pure virtual

Returns the probability calculated by the inference process.

Returns

Probability for this scene.

Implements ProbabilisticSceneRecognition::InferenceAlgorithm.

Implemented in ProbabilisticSceneRecognition::MaximumBackgroundInferenceAlgorithm, ProbabilisticSceneRecognition::PowerSetBackgroundInferenceAlgorithm, ProbabilisticSceneRecognition::SummarizedBackgroundInferenceAlgorithm, and ProbabilisticSceneRecognition::MultipliedBackgroundInferenceAlgorithm.

void ProbabilisticSceneRecognition::BackgroundInferenceAlgorithm::load ( boost::property_tree::ptree &  pPt )

virtual

Loads the model from an XML file.

Parameters

pPt	Data structure for performing XML operations.
