Detailed Description

template<typename T>
struct DGtal::concepts::CSurfelLocalEstimator< T >

Aim: This concept describes an object that can process a range of surfels (that are supposed to belong to some (abstract) surface) so as to return one estimated quantity for each element of the range (or a given subrange).

Description of concept 'CSurfelLocalEstimator'

It is rather general in the sense that it does not impose a type for the shape under study. It may be a digital surface, a point predicate that defines implicitly a digital shape, an implicit function, etc. This concept has refinements specifying some cases.

Refinement of

• boost::DefaultConstructible, boost::CopyConstructible, boost::Assignable

Associated types

• Surfel : the type of elements of the surface
• Quantity : the type of the (geometric) quantity that is estimated, must be a model of CQuantity.

Notation

• X : A type that is a model of CSurfelLocalEstimator
• x : object of type X
• h : double
• itb, ite, it,itb2, ite2 : instances of a model of forward iterators having Surfel as value type.
• ito : an instance of a model of output iterator having Quantity as value type

Definitions

Valid expressions and semantics

Name	Expression		Return type	Precondition	Semantics		Complexity
Initialization	x.init( h, itb, ite )		void	h > 0	Grid step and range initialization in [itb,ite)		model dependent
Evaluation	x.eval( it )		Quantity		Estimation of the quantity at it, which must belong to [itb,ite)		model dependent
Evaluation	ito = x.eval( itb2, ite2, ito )		a model of output iterator		Estimation for each element of [itb2, ite2), which must be a subrange of or the whole range [itb,ite)		model dependent
gridstep accessor	x.h()		double		Accessor to the gridstep value		O(1)
