REPARAMETRIZATION OF NURBS CURVES
International Journal of Shape Modeling, 1996The authors note that it is difficult to work with arc length for parametrically given curves, in particular the rationality of the representation is lost for NURBS curves. Hence, they propose a reparametrization scheme that approximates parametrization by arc length \(\varphi(t)\) through a fractional linear transformation \(\psi(t)\) such that \(\psi\

Reparametrization in deep learning
, 2018 L'apprentissage profond est une approche connectioniste à l'apprentissage automatique. Elle a pu exploiter la récente production massive de données numériques et l'explosion de la quantité de ressources computationelles qu'a amené ces dernières décennies.

Numerical Proper Reparametrization of Space Curves and Surfaces [PDF]
CAD Computer Aided Design, 2019 Simplifying rational parametrizations of surfaces is a basic problem in CAD (computer-aided design). One important way is to reduce their tracing index, called proper reparametrization.

Fast Adaptive Reparametrization (FAR) With Application to Human Action Recognition [PDF]
IEEE Signal Processing Letters, 2020 peer reviewedIn this paper, a fast approach for curve reparametrization, called Fast Adaptive Reparamterization (FAR), is introduced. Instead of computing an optimal matching between two curves such as Dynamic Time Warping (DTW) and elastic distance ...

Numerical proper reparametrization of parametric plane curves [PDF]
Journal of Computational and Applied Mathematics, 2015 We present an algorithm for reparametrizing algebraic plane curves from a numerical point of view. More precisely, given a tolerance ϵ>0 and a rational parametrization P of a plane curve C with perturbed float coefficients, we present an algorithm that ...

CLOSURE OF REPARAMETRIZATION ALGEBRAS AND FLOW DEPENDENCE OF FINITE REPARAMETRIZATIONS
International Journal of Modern Physics A, 1994The reparametrization algebra in one dimension and some of its generalizations are studied by applying certain developments on formal integration of infinitesimal gauge transformations. The closure of these algebras is related to the finite form of the reparametrizations; more precisely, to its dependence on the flow of the infinitesimal ...

A partial solution to the problem of proper reparametrization for rational surfaces [PDF]
Computer Aided Geometric Design, 2013 Given an algebraically closed field K, and a rational parametrization P of an algebraic surface V ⊂ K3 , we consider the problem of computing a proper rational parametrization Q from P (reparametrization problem).
