Thin Plate Spline Network with Radiohead Example

Thin plate splines can be used to interpolate nonuniform data, such as the Radiohead dataset, which

Description

A thin plate spline radial basis function network may be used to interpolate non-uniformly spaced data. The surface (or line or hypersurface) is fit exactly to the given control points, with the surface in between acting similar to thin sheet of metal.
An example is given using a frame of data from the Radiohead "House of Cards" video dataset, if which the point cloud is interpolated onto a uniform grid for plotting with the surf function.
A simpler example is also included.

• MATLAB release: MATLAB 7.4 (R2007a)
• Other requirements: The default Radioheadhead example should run on most modern computers. If one wishes, the resolution and accuracy may be increased, at the expense of memory and computation time.

A very good example of a powerful technique. The function network may be used to generate a grid for other types of analysis.
