Detailed Description

template<typename TSegmentComputer, typename Functor, typename ReturnType = typename Functor::Value>
class DGtal::detail::PosIndepScaleIndepSCEstimator< TSegmentComputer, Functor, ReturnType >

Description of class 'PosIndepScaleIndepSCEstimator'

Aim: estimates a geometric quantity from a segment computer. The estimation is neither position-dependent nor scale-dependent (e.g. tangent or normal estimation from 'straight' primitives).

Template Parameters
TSegmentComputera model of segment computer.

The computation is delegated to a functor.

Template Parameters
Functora unary functor

This class is a model of CSegmentComputerEstimator
