Thin plate splines transformation
WebPrincipal warps: thin-plate splines and the decomposition of deformations Abstract: The decomposition of deformations by principal warps is demonstrated. The method is extended to deal with curving edges between landmarks. This formulation is related to other applications of splines current in computer vision. WebNevertheless, differences between thin-plate splines with and without covariates are apparently less important than in day LST and night LST, but only because the range of the NDVI variable is smaller than that of LST. Summarizing, all the figures show lower RMSE when using covariates in both thin-plate splines (Tps) and state-space models (SSM).

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.
