Detailed Description

template<typename DSSComputer>
class DGtal::CurvatureFromDSSLengthEstimator< DSSComputer >

Description of class 'CurvatureFromDSSLengthEstimator'

Aim: estimates the curvature from a DSS recognized by a segment computer.

The curvature \( k \) is defined from the discrete length \( l \) of a DSS as follow: \( 1/k = l*l/8 + 1/2 \)

Note
Adaption from Coeurjolly, D. and Miguet, S. and Tougne, L. "Discrete Curvature Based on Osculating Circle Estimation", Proc. IWVF, LNCS, vol 2059, pp.303-312, 2001

In this approach, the DSS is viewed as the chord at a distance h (the grid step) to the osculating circle. Unfortunately, maximal DSS are in general too short.

Template Parameters
DSSComputera model of segment computer devoted the DSS recognition
