Polynomial splines as examples of Chebyshevian splines [PDF]
Numerical Algorithms, 2012 Spaces of geometrically continuous (piecewise defined) functions are considered in this paper. Such functions in use for approximation purposes of all sorts may be piecewise polynomials or more generally coming from extended Chebyshev spaces. The latter are natural generalisations of polynomial spline structures.

Comparison Between T-Spline Surface and NURBS Surface [PDF]
Engineering and Technology Journal, 2015 This research uses T-spline for surface modeling and compares it with NURBS modeling to get the best modeling points between the two methods. The comparison will be through surface analysis and manufacturing process.T-Splines surfaces typically have 50 ...

Verification of the Spline Method and its Application to Curvilinear Objects
Technical Transactions, 2019 Two methods of interpolation are presented in this article: interpolation with the help of orthogonal polynomials and interpolation on a cubic spline path (with the help of glued-together functions).

Journal of Forest Science, 2015 Generalized additive models were tested using three types of smoothing functions as an alternative for modelling the height curve. The models were produced for 23 forest stands of Norway spruce (Picea abies [L.] Karst.) in the territory of the Training ...

Surgery of spline-type and molecular frames [PDF]
, 2009 We prove a result about producing new frames for general spline-type spaces by piecing together portions of known frames. Using spline-type spaces as models for the range of certain integral transforms, we obtain results for time-frequency decompositions

Volumetric Untrimming: Precise decomposition of trimmed trivariates into tensor products
, 2019 3D objects, modeled using Computer Aided Geometric Design tools, are traditionally represented using a boundary representation (B-rep), and typically use spline functions to parameterize these boundary surfaces.

Simultaneous Approximation of a Multivariate Function and its Derivatives by Multilinear Splines [PDF]
, 2013 In this paper we consider the approximation of a function by its interpolating multilinear spline and the approximation of its derivatives by the derivatives of the corresponding spline.

Splines for diffeomorphisms [PDF]
Medical Image Analysis, 2015 This paper develops a method for higher order parametric regression on diffeomorphisms for image regression. We present a principled way to de ne curves with nonzero acceleration and nonzero jerk. This work extends methods based on geodesics which have been developed during the last decade for computational anatomy in the large deformation ...
