WebSeveral packages are available in R to conduct interpolation by kriging, including “kriging” (simple package covering ordinary kriging), “gstat” (enables many forms of kriging including ordinary, universal, block, etc.), “geoR” and “geoRglm” (for Bayesian kriging). Below are some resources that pertain to the “kriging” and ...

WebBivariate and trivariate functions for interpolation from scattered data are derived. They are constructed by explicit minimization of a general smoothness functional, and they include a tension parameter that controls the character of the interpolation function (e.g., for bivariate case the surface can be tuned from a “membrane” to a “thin steel plate”), Tension can … WebThe thin plate spline (TPS) is an effective tool for modeling coordinate transformations that has been applied successfully in several computer vision applications. Unfortunately the solution requires the inversion of a p × p matrix, where p is the number of points in the data set, thus making it impractical for large scale applications. derby university harvard referencing

Google Scholar WebA weight of zero results in the basic thin plate Spline interpolation. Using a larger value of weight reduces the stiffness of the plate, and in the limit as phi approaches infinity, the surface approximates the shape of a membrane or rubber sheets, passing through the points. The interpolated surface is smooth.
