Tangent estimation along 3D digital curves

Abstract : In this paper, we present a new three-dimensional (3D) tangent estimator by extending the two-dimensional (2D) λ-maximal segment tangent (λ-MST) estimator, which has very good theoretical and practical behaviors. We show that our proposed estimator keeps the same time complexity, accuracy and experimental asymptotic behaviors as the original 2D one.
