Detailed Description

Thin-plate-spline 3-D warp fitted from landmark correspondences.

Thin-plate-spline (Bookstein) 3-D warp that maps source landmarks exactly onto destination landmarks and extends smoothly to the rest of R^3. Used for non-rigid registration of EEG/MEG sensors and template-to-subject mesh warping.
