Detailed Description

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

Description of class 'PosDepScaleIndepSCEstimator'

Aim: estimates a geometric quantity from a segment computer. The estimation is not scale dependent but position dependent (e.g. tangent or normal estimation from high-order primitives).

Template Parameters
TSegmentComputera model of segment computer.

The computation is delegated to a functor.

Template Parameters
Functora binary functor

This class is a model of CSegmentComputerEstimator
