We also provide the option to perform regularized interpolation. Here, the interpolant is selected to trade off between the squared loss on the training data and a certain measure of its curvature . Using a regularization weight greater than zero has the effect that the interpolant will ...

WebTo compute a spline, the analyst must specify: 1.the order of the spline; most commonly cubic splines (4th order); 2.the number of knots; 3.the placement of knots in the range of … WebThin Plate Spline, or TPS for short, is an interpolation method that finds a "minimally bended" smooth surface that passes through all given points. TPS of 3 control points is a plane, more than 3 is generally a curved surface and less than 3 is undefined.

WebDec 8, 2024 · Thin Plate Spline. We can define the Thin Plate Spline technique as a transformation where we use control points to transform a space. In this case our space is the image that we want to augment. The following one is the TPS equation: Where p is the number of control points that we have, in our case is the number of pixels of the image.
