Detailed Description

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

Description of class 'PosIndepScaleDepSCEstimator'

Aim: estimates a geometric quantity from a segment computer. The estimation is not position-dependent, but is scale-dependent (e.g. curvature or radius estimation from 'circular' primitives).

Template Parameters:

TSegmentComputer

a model of segment computer.

The computation is delegated to a functor.

Template Parameters:

Functor

a binary functor

This class is a model of CSegmentComputerEstimator
