Realtime curve interpolators
The amount of geometric information that must be transferred between a CAD system and a computerized numerical control system creates a conflict between part precision on the one hand and feedrate fidelity and communications load on the other. This is the motivation for the development of new curve interpolation algorithms for CNC. The interpolation dependson the method of curve representation,...
متن کاملContour Following Using C PH Quintic Spline Curve Interpolators
This paper presents a C Pythagorean-Hodograph (PH) spline curve interpolator for contourfollowing tasks. To generate the C PH quintic spline curve, a uniform knot sequence is employed. The Scurve motion planning architecture with variable feedrate for a planar C PH quintic spline curve is also developed. In particular, C cubic feed acceleration/deceleration is imposed on the first and last PH q...
متن کاملPde-based Image Interpolators
We present a PDE-based interpolation algorithm to effectively reproduce high resolution imagery. Conventional PDE-based interpolation methods can produce sharp edges without checkerboard effects; however, they are approximators and tend to weaken fine structures. In order to overcome the drawback, a texture enhancement method is incorporated as a post-process of PDE-based interpolation methods....
متن کامل2 Definition of Barycentric Interpolators
In order to nd the optimal control of continuous state-space and time reinforcement learning (RL) problems, we approximate the value function (VF) with a particular class of functions called the barycentric interpolators. We establish su cient conditions under which a RL algorithm converges to the optimal VF, even when we use approximate models of the state dynamics and the reinforcement functi...
متن کاملPrinciples of Deterministic Spatial Interpolators
Resumo: A interpolação espacial é o processo de prever o valor de atributos em locais não amostrados a partir de medições realizadas em localizações diversas de uma determinada região [Burrough, McDonnell, 1998]. Rever e comparar os interpoladores determinísticos espaciais usados em Sistemas de Informação Geográficos (GIS) como a B-Spline, Fourier, TIN, IDW e as superfícies de tendência polinom...
