A fitting approach with dynamic algebraic spline curves

Ninth International Conference on Computer Aided Design and Computer Graphics (CAD-CG'05), 2005
In computer aided geometric design and computer graphics, fitting point clouds with smooth curves (known as curve reconstruction) is a widely investigated problem. Dynamic implicit curve reconstruction is a new approach appearing in the curve reconstruction.

The linear algebra of box spline spaces

1993
In this chapter, we consider the cardinal spline space $$S: = {S_M}: = span{\left( {M\left( { \cdot - j} \right)} \right)_{j{ \in ^s}}}$$ (1) i.e., the space spanned by the shifts, or integer translates, of the box spline \(M: = {M_\Xi }.\)

A Class of Algebraic Trigonometric Interpolation Splines and Applications

2010 International Conference on Computational and Information Sciences, 2010
A new kind of interpolation splines with a shape parameter over the algebraic trigonometric function space Ω=span {1, t, sint, cost, sint2t, cos2t} is presented, which are called cubic algebraic trigonometric splines. The cubic algebraic trigonometric splines have many similar properties to cubic B-splines.

Algebraic Proof of the B-Spline Derivative Formula

2005
We prove a well known formula for the generalized derivatives of Chebyshev B--splines: \begin{; ; ; eqnarray*}; ; ; L_1B_i^k(x) & = & \frac{; ; ; B_i^{; ; ; k-1}; ; ; (x)}; ; ; {; ; ; C_{; ; ; k-1}; ; ; (i)}; ; ; - \frac{; ; ; B_{; ; ; i+1}; ; ; ^{; ; ; k-1}; ; ; (x)}; ; ; {; ; ; C_{; ; ; k-1}; ; ; (i+1)}; ; ; , \end{; ; ; eqnarray*}; ; ; where \begin{;
