Malaysia's rainfall and Kalumpang agricultural station data for scattered data interpolation [PDF]

Data in Brief
Scattered data interpolation is an essential technique used in environmental, geospatial and meteorological analysis. It enables the estimation of unknown values within a dataset at the domain by utilising known data points.

Scattered Data Interpolation Using Rational Quartic Triangular Patches With Three Parameters

IEEE Access, 2020
This paper discusses the construction of scattered data interpolation scheme based on rational quartic triangular patches with C1 continuity. The C1 sufficient condition is derived on each adjacent triangle. We employ rational corrected scheme comprising

Meshfree Interpolation of Multidimensional Time-Varying Scattered Data

Computers, 2023
Interpolating and approximating scattered scalar and vector data is fundamental in resolving numerous engineering challenges. These methodologies predominantly rely on establishing a triangulated structure within the data domain, typically constrained to

Construction of new cubic Bézier-like triangular patches with application in scattered data interpolation

Advances in Difference Equations, 2020
This paper discusses the functional scattered data interpolation to interpolate the general scattered data. Compared with the previous works, we construct a new cubic Bézier-like triangular basis function controlled by three shape parameters.

An Adaptive Selection Method for Shape Parameters in MQ-RBF Interpolation for Two-Dimensional Scattered Data and Its Application to Integral Equation Solving

Fractal and Fractional, 2023
The paper proposes an adaptive selection method for the shape parameter in the multi-quadratic radial basis function (MQ-RBF) interpolation of two-dimensional (2D) scattered data and achieves good performance in solving integral equations (O-MQRBF).

Cubic q-Bézier Triangular Patch for Scattered Data Interpolation and Its Algorithm

Algorithms
This paper presents an approach to scattered data interpolation using q-Bézier triangular patches via an efficient algorithm. While existing studies have formed q-Bézier triangular patches through convex combination, their application to scattered data ...

Construction of Cubic Timmer Triangular Patches and its Application in Scattered Data Interpolation

Mathematics, 2020
This paper discusses scattered data interpolation by using cubic Timmer triangular patches. In order to achieve C1 continuity everywhere, we impose a rational corrected scheme that results from convex combination between three local schemes.

Kernel Interpolation of High Dimensional Scattered Data [PDF]

SIAM Journal on Numerical Analysis, 2020
Data sites selected from modeling high-dimensional problems often appear scattered in non-paternalistic ways. Except for sporadic clustering at some spots, they become relatively far apart as the dimension of the ambient space grows. These features defy any theoretical treatment that requires local or global quasi-uniformity of distribution of data ...

Anisotropic Scattered Data Interpolation for Pushbroom Image Rectification

IEEE Transactions on Image Processing, 2014
This paper deals with fast and accurate visualization of pushbroom image data from airborne and spaceborne platforms. A pushbroom sensor acquires images in a line-scanning fashion, and this results in scattered input data that need to be resampled onto a uniform grid for geometrically correct visualization. To this end, we model the anisotropic spatial

A novel triangle-based method for scattered data interpolation [PDF]

Applied Mathematical Sciences, 2014
Local numerical methods for scattered data interpolation often require a smart subdivision of the domain in geometrical polyhedral structures. In particular triangulations in the plane (2D) and tetrahedrizations in the space (3D) are widely used to dene interpolation models.
