A Geometric Approach for Knot Selection in Convexity-Preserving Spline Approximation

Abstract

A geometric approach is proposed for selecting the knots used in a parametric convexity-preserving B-spline approximation scheme. The approach automatically gives the necessary information about the shape suggested by the data which may be exact or not.
