The inversion problem for rational B\'ezier curves

Numerical Analysis 2010-07-19 v1

Abstract

The inversion problem for rational B\'ezier curves is addressed by using resultant matrices for polynomials expressed in the Bernstein basis. The aim of the work is not to construct an inversion formula but finding the corresponding value of the parameter for each point on the curve. Since sometimes one has only an approximation of that point the use of the singular value decomposition, a key tool in numerical linear algebra, is shown to be adequate.
