Convergence of binomial-based derivative estimation for C-2 noisy discretized curves
We present a derivative estimator for discrete curves and discretized functions which uses convolutions with integer-only binomial masks. The convergence results work for C-2 functions, and as a consequence we obtain a complete uniform convergence result for parameterized C-2 curves for derivatives of any order. (C) 2011 Elsevier B.V.
