Web13 May 2024 · I have tried both my own written-code and in-built python module to perform "Thin-Plate-spline" interpolation and both the results are showing same "Quadrupole" kind … WebThin plate splines are one approach. A set of basis functions emerges directly from the demand to minimize the residual sum of squares, plus a smoothness penalty that is a multiple of the multivariate integral over the space spanned by the explanatory variables of a suitable smoothness function.

Rewrite from daeyun/TPS-Deformation, which was originally matlab code. Usage Use tps.find_coefficients to get coefficients, and then you can transform other points from source surface to the deformed surface by using tps.tps.transform. Or one could use the shortcut tps.TPS (see example below). marty kumm electrical seminars https://lovetreedesign.com

Web4 Jan 2024 · Here is a reasonably simple implementation of thin-plate spline image warping I wrote ten years ago or so. It follows the notation from Bookstein's original paper, if that helps. It's not fast to define the transform, so there's an option to compute a downscaled transform and then interpolate linearly.
