Detailed Description

template<typename TKSpace, typename TImage>
class DGtal::functors::FrontierPredicate< TKSpace, TImage >

Aim: The predicate on surfels that represents the frontier between two regions in an image. It can be used with ExplicitDigitalSurface or LightExplicitDigitalSurface so as to define a digital surface. Such surfaces may of course be open.

Description of class 'FrontierPredicate'

Template Parameters

TKSpace	any model of cellular space
TImage	any model of Image

Examples: geometry/volumes/distance/exampleFMM3D.cpp, topology/frontierAndBoundary.cpp, and tutorial-examples/FMMErosion.cpp.

Constructor & Destructor Documentation

◆ ~FrontierPredicate()

template<typename TKSpace , typename TImage >

DGtal::functors::FrontierPredicate< TKSpace, TImage >::~FrontierPredicate ( )

Destructor.

◆ FrontierPredicate() [1/2]

template<typename TKSpace , typename TImage >

DGtal::functors::FrontierPredicate< TKSpace, TImage >::FrontierPredicate	(	ConstAlias< KSpace >	aSpace,
		ConstAlias< Image >	anImage,
		const Value &	l1,
		const Value &	l2 )

Constructor. The frontier will be defined only with the image domain. The space must be large enough to contain the frontier.

Parameters

aSpace	a cellular grid space (referenced).
anImage	any image (referenced).
l1	a label in the image that defines the inner region.
l2	a label in the image that defines the outer region.

◆ FrontierPredicate() [2/2]

template<typename TKSpace , typename TImage >

DGtal::functors::FrontierPredicate< TKSpace, TImage >::FrontierPredicate ( const FrontierPredicate< TKSpace, TImage > & other )

Copy constructor.

Parameters

other the object to clone.
