WebA thin plate smoothing spline is a generalization of the cubic smoothing spline, and depends on two parameters: m, the order of the derivative penalty, and , a parameter controlling the amount of smoothing. For the case of one dimension and m = 2, the estimate reduces to the usual cubic spline. Webof the natural cubic splines in 1D.

Thin plate splines (TPS) are a spline-based technique for data interpolation and smoothing. They were introduced to geometric design by Duchon. They are an important special case of a polyharmonic spline. Robust Point Matching (RPM) is a common extension and shortly known as the TPS-RPM algorithm.
