Detailed Description

template<typename SegmentComputer, typename SCEstimator>
class DGtal::MostCenteredMaximalSegmentEstimator< SegmentComputer, SCEstimator >

Aim: A model of CLocalCurveGeometricEstimator that assigns to each element of a (sub)range a quantity estimated from the most centered maximal segment passing through this element.

Description of template class 'MostCenteredMaximalSegmentEstimator'

Here is a basic example of curvature estimation:

1. Construct an instance from a segment computer and a segment computer estimator
typedef StabbingCircleComputer<ClassicIterator> SegmentComputer;

typedef CurvatureFromDCAEstimator<SegmentComputer> SCEstimator;

typedef MostCenteredMaximalSegmentEstimator<SegmentComputer,SCEstimator> CurvatureEstimator;

SegmentComputer sc;

SCEstimator sce;

CurvatureEstimator estimator(sc, sce);
