With the default, second derivative penalty we see that under extrapolation, the spline exhibits linear behaviour. WebPython implementation of thin plate spline 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).
