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.
