27 Feb 2014 Thin Plate Spline Network with Radiohead Example Thin plate splines can be used to interpolate nonuniform data, such as the Radiohead dataset, which Author: Travis Wiens Verveld, Mark

Thanks for sharing, I like the examples.

Some constructive criticism:
You should really consider vectorizing this. In Matlab, whenever possible, avoid loops.

I just got a 66 fold reduction in computation time on the Radiohead example with N_t 3000 and N_grid 250. (From 626 s to 9.45 s)

Also, it is easy to generalize TPS to m-dimensional values in an n-dimensional domain. That is what makes the method so powerful IMO.

You should give the links to the required files (rotate_image, imclipboard).
