WebThin plate spline regression Description Fits a thin plate spline surface to irregularly spaced data. The smoothing parameter is chosen by generalized cross-validation. The assumed … 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 fitted surface. In the physical setting, the deflection is in the direction, orthogonal to the plane. In order to apply this idea to the problem of coordinate transformation, one interprets the lifting of the plate as a displacement of the or coordinates within the plane. In 2…

Weba L-spline approach, we nd two types of minimizing pro les: one is the limit of Rabut’s solution as R 1!0 and R 2!1(identi ed as a ‘non-singular’ L-spline), the other has a second-derivative singularity and matches an extra data value at 0. For both pro les and p 2[2;1], we establish the Lp-approximation order 3=2+1=p in the radial energy ... WebThe spline curve represents a thin metal rod that is constrained not to move at the sample points x i. The concept applies equally as well in two dimensions. A thin-plate spline is a physically motivated 2D inter-polation scheme for arbitrarily spaced tabulated data (x i;y i;f(x i;y i)). These splines are the generalization WebFeb 1, 2024 · One can also fit a thin plate spline to the same data by: p=1; st=tpaps ( [xData',yData'],zData',p) The resulting structure, st, includes st.coefs, which is a vector of 12 coefficients. By setting p=1, tpaps () returns an exact-fitting thin plate spline. As p decreases toward 0, the fit becomes increasingly approximate. showgroundslive rmsj
