Principles of local polynomial interpolation

2008 37th IEEE Applied Imagery Pattern Recognition Workshop, 2008
The sub-pixel analysis of large volumes of digital imagery requires precise methods of interpolation. To be computationally feasible, the methods must be massively parallelizable, and this constrains them to be local. This paper develops a set of principles for generating local interpolators, which apply to both one and higher-dimensional problems. The

A smooth local polynomial model of vignetting

2017 22nd International Conference on Methods and Models in Automation and Robotics (MMAR), 2017
The vignetting is one of image distortions, which refers to the fall-off of pixel intensity due to optical properties of the camera and lens system. The effect of vignetting on image is unwanted in image processing and analysis. The vignetting of the camera-lens system can be determined using the vignetting model.

Locally Invertible Multivariate Polynomial Matrices

2006
A new class of rectangular zero prime multivariate polynomial matrices are introduced and their inverses are computed. These matrices are ideal for use in multidimensional systems involving input-output transformations. We show that certain multivariate polynomial matrices, when transformed to the sequence space domain, have an invertible subsequence ...

Local Polynomial Estimate of Surface Laplacian

Brain Topography, 1999
This paper describes a method for estimating the surface Laplacian of brain potentials. The method consists of two steps: local surface approximation by its tangent plane and local polynomial fitting. Compared to previous methods for estimating surface Laplacian, this method has some new features.

LOCALLY POLYNOMIAL RINGS AND SYMMETRIC ALGEBRAS

Mathematics of the USSR-Izvestiya, 1977
In this paper we prove that every finitely generated locally polynomial algebra over a ring having only a finite number of minimal prime ideals is isomorphic to the symmetric algebra of a finitely generated projective module. We also obtain some other results on the structure of locally polynomial algebras.Bibliography: 8 titles.

Dimension polynomials of difference local algebras

Advances in Applied Mathematics, 2016
Difference dimension polynomials, if they exist, are a useful tool for obtaining new results on the structure of difference algebras (see, for example, [\textit{A. B. Levin}, Difference algebra. New York: Springer (2008; Zbl 1209.12003), Section 4.6]).
