An application of the Shepard operator in image reconstruction
Abstract We propose an application of the Shepard operator combined with two radial basis functions in image processing. This method…
Spherical Shepard-Bernoulli operator
AbstractWe consider the problem of interpolating large sets of scattered data on the sphere using Shepard-Bernoulli operators constructed based on…
Spherical interpolation of scattered data using least squares thin-plate spline and inverse multiquadric functions
Abstract We construct some smooth functions defined over a sphere that interpolate large sets of scattered data, using some modified…
Iterative Shepard operator of least squares thin-plate spline type
AbstractWe propose a modified bivariate Shepard operator of least squares thin-plate spline type based on an iterative method, introduced by…
