RegionDiameter


Computes the longest segment connecting two pixels contained in region and its length.

Syntax

C++
C#
 
void avl::RegionDiameter
(
	const avl::Region& inRegion,
	atl::Optional<avl::Segment2D&> outDiameter = atl::NIL,
	atl::Optional<float&> outDiameterLength = atl::NIL
)

Parameters

Name Type Default Description
inRegion const Region& Input region
outDiameter Optional<Segment2D&> NIL
outDiameterLength Optional<float&> NIL

Description

The operation finds the most distant pair of region pixels and returns the distance between them (outDiameterLength) and the segment representing the diameter (outDiameter). If there is more than one pair of maximal distance, the returned segment will correspond to one of them. The orientation of the resulting outDiameter is always between 0 and 180 degrees.

Hints

  • If the input region is not guaranteed to be non-empty, precede this filter with SkipEmptyRegion.

Examples

The resulting outDiameterLength = 276.4815, outDiameter segment was drawn onto the region.

Errors

Error type Description
DomainError Empty region in RegionDiameter
