CINAPACT-Splines: A Family of Infnite Smooth, Accurate and Compactly Supported Splines
… compactly supported C infinite kernels (CINAPACT-splines) whose integer translates form a shift-invariant reconstruction space that can be tuned to achieve any order of accuracy. CINAPACT-splines resemble traditional B-splines in that higher orders of accuracy are achieved by successive …

Delaunay Configuration B-Splines
The generalization of univariate splines to higher dimensions is not straightforward. There are different approaches, each with its own advantages and drawbacks. A promising approach using Delaunay configurations and simplex splines is due to Neamtu. After recalling fundamentals of univariate …

Arbitrary Degree T-Splines
<p>T-Splines is a freeform surface type similar to NURBS, that allows partial rows of control points. Up until now, T-Splines have only been formally defined for the degree three case. This paper extends the definition to support all odd, even, and mixed degree T-Spline surfaces, making T-Splines a …

Splines on polytopal complexes
… of $C^r$ piecewise polynomial functions (splines) over a subdivision by convex polytopes $\PC$ of a domain $\Omega\subset\R^n$. Interest in this algebra arises in a wide variety of contexts, ranging from approximation theory and computer-aided geometric design to equivariant cohomology and …

Chebyshev Approximation of Discrete polynomials and Splines
… the discrete domain should increase the use of B-splines in many applications. Because we show here how the impulse/summation approach can also be used for constructing polynomials, the approach with a search table approach for the inverse square root operation allows an efficient shading …

Algebraic Grid Generation Using Tensor Product B-Splines
… algorithm uses a mapping composed of bicubic B-splines. Boundary coefficients are chosen so that the splines produce Schoenberg's variation diminishing spline approximation to the boundary. Interior coefficients are initially chosen to give a variation diminishing approximation to the …

Splines de regressão adaptativa multivariada na predição genômica
… Uma metodologia ainda não explorada em SGA é a Splines de Regressão Adaptativa Multivariada (MARS). A MARS modela efeitos individuais e possíveis interações entre variáveis preditoras, podendo ser particularmente útil para SGA considerando efeitos não aditivos. Diante disso o objetivo deste …

Dynamic Multivariate Simplex Splines For Volume Representation And Modeling
… framework based on dynamic multivariate simplex splines (DMSS) that can greatly improve the accuracy and efficacy of modeling and simulation of heterogenous objects. The framework can not only reconstruct with high accuracy geometric, material, and other quantities associated with heterogeneous …

Accurate geometry reconstruction of vascular structures using implicit splines
3-D visualization of blood vessel from standard medical datasets (e.g. CT or MRI) play an important role in many clinical situations, including the diagnosis of vessel stenosis, virtual angioscopy, vascular surgery planning and computer aided vascular surgery. However, unlike other human organs, …
