Member Function Documentation

◆ computeDiameters()

static int computeDiameters	(	Graph &	graph,
		const SharedImage &	labelMap,
		bool	useAveragedValues = true,
		double	threshold = 0.5 )

static

Compute diameters of edges in a graph.

This is done by choosing the largest possible diameter so that a (filled) circle of this diameter normal to the edge has only nonzero label values in the label map.

◆ computeVesselDiameters()

static int computeVesselDiameters	(	Graph &	graph,
		const SharedImage &	labelMap,
		bool	clampEdges,
		std::optional< int >	slidingAverage,
		double	threshold = 0.5 )

static

Compute diameters of edges in a graph.

This is done by choosing the largest possible diameter so that a (filled) circle of this diameter normal to the edge has only nonzero label values in the label map.

◆ compute()

void compute ( )

overridevirtual

Execute the algorithm.

Implements Algorithm.

◆ takeOutput()

OwningDataList takeOutput ( )

overridevirtual

Return any new Data that was created by the Algorithm during the last call to compute().

The default implementation will return an empty list.

Note: Since ownership of the data is transferred, you can call this method only once between calls to compute().

Reimplemented from Algorithm.

The documentation for this class was generated from the following file:
