Member Function Documentation

void opentl::modalities::Likelihood::addChild	(	Modality *	childFeature,
		core::cvdata::T_LEVEL	childOutputLevel
	)

Adds a child Feature class as input ATTENTION: In order to avoid code duplication related to data fusion, the Likelihood supports a single child ONLY! If data fusion of multiple Feature instances is required, add a DataFusion instance as child.

Parameters:

	childFeature	pointer to a modality instance
	childOutputLevel	output level of the modality used for computing the likelihood

Likelihood* opentl::modalities::Likelihood::clone

(

)

const

Clone this Likelihood instance.

int opentl::modalities::Likelihood::explicitModel	(	const TargetPtrVector &	targets,
		T_MEAS_LIKPtrVector &	outputMeas,
		int	measComputeFlags,
		std::size_t	partitionIdx
	)

Computes explicit likelihood <E,R,(H)>.

Parameters:

	states
	outputMeas	Measurement structure given by tracker (one set of fused measurements per target).
