Member Enumeration Documentation

Enumeration for different region weightings.

Enumerator:

Equal	Equal weighting of all regions.
Volume	Weighting of regions proportional to volume.
VolumeInverse	Weighting of regions proportional to inverse volume.

size_t cmtk::OverlapMeasures::ComputeGroupwiseOverlap	(	double &	overlapEqualWeighted,
		double &	overlapVolumeWeighted,
		double &	overlapInverseWeighted
	)		const `[inline]`

Compute simple groupwise overlap.

Returns:: Number of labels included in computation. If this is zero, the resulting overlap values are invalid.

Parameters:

overlapEqualWeighted	Equal-weighted overlap score is returned herein.
overlapVolumeWeighted	Volume-weighted overlap score is returned herein.
overlapInverseWeighted	Inverse volume-weighted overlap score is returned herein.

unsigned int cmtk::OverlapMeasures::GetMaxLabelValue ( ) const [inline]

Return maximum label value used in data.
