WebMay 28, 2024 · A TPS basis has as many basis functions as unique data values in X. What Wood (2003) showed was that you can create a Thin Plate Regression Spline (TPRS) basis uses an eigendecomposition of the the TPS basis functions, and retaining only the first k … Web3.1 The thin-plate spline algorithm Thin thin -plate algorithm is solved by minimizing the bending energy below [1]. The basis for solving the algorithm is given by a kernel function U as: U = r²log(r²), where r = (x a – x b)² + (y a – y b)² Given a set of source landmark points, we define P as a matrix of (3 x n) where n is the number ...

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.
