Reconstruction and smoothing of polygonal curves

Abstract

In this paper we propose a method for piecewise linear reconstruction and subsequent smoothing of a point sampled curve. The reconstruction step is based on the meshless parameterization reconstruction algorithm proposed by Floater. The information computed in the reconstruction step is used for a least squares based discrete smoothing method, with behavior comparable to a smoothing spline. We discuss smoothing under two different constraints: one based on the sum of squared deviations and the other based on a max-norm error. The smoothing algorithm is essentially a variation on the least squares meshes concept proposed by Sorkine et al. The reconstruction and smoothing steps are conceptually similar and provide a unified approach to the reconstruction of smooth curves in an arbitrary dimensional space.
