RBF Moment computation and meshless cubature on general polygonal regions

چکیده
We obtain analytical formulas for the computation of integrals (moments) all most common Radial Basis Functions (usually shortened as RBFs) on polygonal regions that may be nonconvex or even multiply connected. With RBFs finite regularity, such Thin-Plate Splines, Wendland functions and Powers, our Matlab codes, based standard linear solvers corresponding moment matching systems, provide cubature rules are reasonably accurate numerically stable.

Gauss-Green cubature and moment computation over arbitrary geometries
We have implemented in Matlab a Gauss-like cubature formula over arbitrary bivariate domains with a piecewise regular boundary, which is tracked by splines of maximum degree p (spline curvilinear polygons). The formula is exact for polynomials of degree at most 2n− 1 using N ∼ cmn2 nodes, 1 ≤ c ≤ p, m being the total number of points given on the boundary. It does not need any decomposition of ...
متن کاملMeshless cubature by Green's formula
By coupling the flexibility of Thin-Plate Splines interpolation with Green’s integral formula, we obtain a meshless cubature method from scattered samples of small/moderate size, on convex as well as nonconvex and even multiply connected polygonal domains. 2000 AMS subject classification: 65D05, 65D32.
متن کاملMeshless Statistical Occlusion Computation
This poster presents a new method to evaluate visibility from a point cloud by using a meshless statistical representation. The resulting evaluation uses much less memory than previous work while still producing high quality images, making it suitable for memory limited systems. The obtained results are exposed through the evaluation of shadow maps using a point cloud created from range images ...
متن کاملA Moment Matrix Approach to Multivariable Cubature
We develop an approach to multivariable cubature based on positivity, extension, and completion properties of moment matrices. We obtain a matrix-based lower bound on the size of a cubature rule of degree 2n+1; for a planar measure μ, the bound is based on estimating ρ(C) := inf{rank (T − C) : T Toeplitz and T ≥ C}, where C := C][μ] is a positive matrix naturally associated with the moments of ...
متن کاملAdaptive meshless centres and RBF stencils for Poisson equation
We consider adaptive meshless discretisation of the Dirichlet problem for Poisson equation based on numerical differentiation stencils obtained with the help of radial basis functions. New meshless stencil selection and adaptive refinement algorithms are proposed in 2D. Numerical experiments show that the accuracy of the solution is comparable with, and often better than that achieved by the me...
