Detailed Description

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

Description of class 'PosDepScaleDepSCEstimator'

Aim: estimates a geometric quantity from a segment computer. The estimation is both position-dependent and scale-dependent (typically distance of a point to an underlying curve).

Template Parameters
TSegmentComputera model of segment computer.

The computation is delegated to a Functor.

Template Parameters
Functora functor

This class is a model of CSegmentComputerEstimator
