is the 1D biharmonic spline interpolation coefficient solved by the following linear system expressed by Equation (8). Fourthly, according to the 1D biharmonic spline interpolation algorithm, the floor altitude of head roadway can be expressed by Equation (9).
Polyharmonic splines are used for function approximation and data interpolation. They are very useful for interpolating and fitting scattered data in many dimensions.

This document describes B-spline interpolation of data organized as uniformly spaced samples on a lattice in multiple dimensions. The B-spline basis functions with oating uniform knots are used for B-spline interpolation of image data.

motivation for Hermite & spline interpolation algorithms. • only cubic PH curves characterizable by simple constraints on Be? zier control polygons. • planar PH cubics = Tschirnhausen’s cubic, spatial PH cubics = { helical cubic space curves } — too limited for general free-form design applications.
Bei der Spline-Interpolation versucht man, gegebene Stutzstellen, auch Knoten genannt, mit Hilfe stuckweiser Polynome niedrigen Grades zu interpolieren. Wahrend das Ergebnis einer Polynominterpolation durch unvorteilhaft festgelegte Stutzstellen oft bis zur Unkenntlichkeit oszilliert 2.3 Cubic spline interpolation. When there are more than four points to be interpolated with cubics, one cannot just put a cubic. The main drawback to the cubic spline interpolation is that changing one of the points interpo-lated will aect the appearance of the curve in segments far removed from the

Finally, The Biharmonic spline interpolation is used to interpolate the all coordinate values and correct the distortional XRII image. The experiment shows that the integrated method can effectively correct the distorted XRII image.
