Thin-plate spline warping
WebThin plate splines and principal/partial warps are irreducibly complex mathematical topics that can only be simplified to provide a general introduction to a certain extent. This is one reason why so few users understand them fully. The good news is there’s only one more warp-based method left to learn, relative warps. WebBigWarp is a tool for manual, interactive, landmark-based deformable image alignment. It uses the BigDataViewer for visualization and navigation, and uses a Thin Plate Spline …

Thin plate splines (TPS) are a spline-based technique for data interpolation and smoothing. They were introduced to geometric design by Duchon. They are an important special case of a polyharmonic spline. Robust Point Matching (RPM) is a common extension and shortly known as the TPS-RPM algorithm.
