Detailed Description

template<bool isCCW = true>
struct DGtal::detail::CurvatureFromDCA< isCCW >

Description of class 'CurvatureFromDCA'

Aim: computes the curvature from a geometricDCA at a given grid step.

Template Parameters

isCCW boolean equal to 'true' for a scanning in a counter-clockwise (CCW) orientation, 'false' otherwise. For instance, the estimated curvature of a digital circle, scanned in a CCW (resp. CW) orientation, is positive (resp. negative).
