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: \( 1/k = l*l/8 + 1/2 \)
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.
