Web1 de mai. de 2015 · In May, Bayesian kriging attained the highest mean S value over the 5 year study period of 0.85, while thin plate smoothing splines attained the lowest mean S value of 0.77. The S values for all interpolation methods were high, demonstrating correlation between the spatial patterns present in the TRMM rasters. Webof this framework given in § 4 and periodic splines are covered in § 5. An interesting recent application of spline methods is to the construction of defor-mations of K2 or K3. Given a pair of objects on which a set of landmarks has been identified, thin-plate splines can be used to construct a deformation taking the 'old' land- 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. how do you test thyroid function
