Two-Dimensional Splines, Surface Splines, Bézier Splines, B-Splines

1996
Assume that we are given a rectangular grid G in the x,y-plane $$ G = \left\{ {\left. {(x_{i,} y_j )\,\,\,\,\,\,\,\,\,\,\,\,\left| \begin{gathered} a = x_0 < x_1 < \ldots < x_n = b \hfill \\ c = y_0 < y_1 < \ldots < y_m = d \hfill \\ \end{gathered} \right.} \right\}} \right. $$ with heights u ij defined at each point \( (x_i ,y_j ) \in G \) $$

Discrete splines and spline filters

IEEE Transactions on Circuits and Systems II: Analog and Digital Signal Processing, 1992
An equation is derived for the Z transform of discrete polynomial splines for the general case of nonuniform knots. Two filter structures are provided for the computation and analysis of discrete splines, one for the one-sided factorial function representation and one for the B-spline representation.

Martensen Splines

BIT Numerical Mathematics, 2006
This paper is concerned with the construction of fundamental functions from the class of Martensen splines. These are Hermite-type polynomial splines in one dimension. The construction provides recursive formulae. Error estimates are presented too.

Splines and Spline Fitting Revisited

1996
This paper presents a detailed summary of the properties and basic facts about spline spaces and their B-spline bases. Examination is made of the many different joint-continuity conditions. Geometric continuity constraints are of special interest, as they appear to satisfy visual needs of the human observers.
