Abstract : An algorithm of estimation of the curvature at each point of a general discrete curve in On.log²n is proposed. It uses the notion of blurred segment, extending the definition of segment of arithmetic discrete line to be adapted to noisy curves. The proposed algorithm relies on the decomposition of a discrete curve into maximal blurred segments also presented in this paper.

Keywords : curvature discrete geometry discrete blurred segments
