Constructor & Destructor Documentation

◆ LambdaMST3DEstimator()

template<typename TSpace, typename TSegmentation, typename Functor>

DGtal::LambdaMST3DEstimator< TSpace, TSegmentation, Functor >::LambdaMST3DEstimator ( )

Default constructor.

Member Function Documentation

◆ accumulate()

template<typename TSpace, typename TSegmentation, typename Functor>

template<typename OutputIterator >

void DGtal::LambdaMST3DEstimator< TSpace, TSegmentation, Functor >::accumulate	(	std::multimap< Point, Value > &	outValues,
		const ConstIterator &	itb,
		const ConstIterator &	ite,
		OutputIterator &	result
	)

protected

Accumulate partial results obtained for each point. In 3D it can happen that DSSs' direction vectors over same point are opposite. To avoid this problem we measure angle between segments' direction vectors and if this angle is bigger than \(\pi/2\), then one of the vectors is reversed. Finally, tangent direction is estimated and stored.

Template Parameters

OutputIterator writable iterator.

Parameters

outValues	partial results for each point
itb	begin iterator
ite	end iterator
result	writable iterator over a container which stores estimated tangent directions.

◆ attach()

void DGtal::LambdaMST3DEstimator< TSpace, TSegmentation, Functor >::attach ( Alias< TSegmentation > segmentComputer )

Parameters

segmentComputer - DSS segmentation algorithm
