Member Function Documentation

virtual modalities::Modality* opentl::modalities::BackgroundSub::clone

(

)

const [virtual]

Clone the current instance.

Returns:

Pointer to a newly created identical instance

Implements opentl::modalities::Modality.

virtual void opentl::modalities::BackgroundSub::init

(

)

[virtual]

Needed init() method for parameter handling.

Reimplemented from opentl::modalities::Modality.

		T_MEAS_PIXPtrVector &	outputMeas,
		std::size_t	partitionIdx
	)			[virtual]

Matching on pixel level

• compare pixel-level image data with expected map, by projecting model data under a predicted state.

Parameters:

	states	Predicted state
	outputMeas	Pixel-space measurement (can be a pixel map of residuals, or a unique residual value)

Reimplemented from opentl::modalities::Modality.

virtual int opentl::modalities::BackgroundSub::preProcess

(

const opentl::core::cvdata::Image &

image

)

[virtual]

Preprocessing and segmentation in order to get model free unassociated data.

Parameters:

sensData

Input sensor data (e.g. camera image in RGB)

virtual void opentl::modalities::BackgroundSub::setAverageTargetArea

(

unsigned int

area

)

[virtual]

Set the average target area for matching.

Parameters:

area

Area to be set
