"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. See more The name thin plate spline refers to a physical analogy involving the bending of a thin sheet of metal. Just as the metal has rigidity, the TPS fit resists bending also, implying a penalty involving the smoothness of the … See more • Elastic map (a discrete version of the thin plate approximation for manifold learning) • Inverse distance weighting See more • Explanation for a simplified variation problem • TPS at MathWorld • TPS in C++ • TPS in templated C++ See more The thin plate spline has a natural representation in terms of radial basis functions.
