A Full-Spectrum Registration Method for Zhuhai-1 Satellite Hyperspectral Imagery
Sensors, 2020 Accurate registration is an essential prerequisite for analysis and applications involving remote sensing imagery. It is usually difficult to extract enough matching points for inter-band registration in hyperspectral imagery due to the different ...

Optimal affine image normalization approach for optical character recognition [PDF]
Компьютерная оптика, 2021 Optical character recognition (OCR) in images captured from arbitrary angles requires preliminary normalization, i.e. a geometric transformation resulting in an image as if it was captured at an angle suitable for OCR. In most cases, a surface containing

Guaranteed Minimum-Rank Solutions of Linear Matrix Equations via Nuclear Norm Minimization [PDF]
, 2007 The affine rank minimization problem consists of finding a matrix of minimum rank that satisfies a given system of linear equality constraints. Such problems have appeared in the literature of a diverse set of fields including system identification and ...

Affine Anosov Diffeomorphims of Affine Manifolds
International Journal of Mathematics and Mathematical Sciences, 2008 We show that a compact affine manifold endowed with an affine Anosov transformation is finitely covered by a complete affine nilmanifold. This is a partial answer of a conjecture of Franks for affine manifolds.

Smoothed affine Wigner transform
Applied and Computational Harmonic Analysis, 2010 We study a generalization of Husimi function in the context of wavelets. This leads to a nonnegative density on phase-space for which we compute the evolution equation corresponding to a Schr odinger equation.

The Maxwell Lagrangian in purely affine gravity [PDF]
, 2008 The purely affine Lagrangian for linear electrodynamics, that has the form of the Maxwell Lagrangian in which the metric tensor is replaced by the symmetrized Ricci tensor and the electromagnetic field tensor by the tensor of homothetic curvature, is ...

2D Cadastral Coordinate Transformation using extreme learning machine technique [PDF]
Geodesy and Cartography, 2018 Land surveyors, photogrammetrists, remote sensing engineers and professionals in the Earth sciences are often faced with the task of transferring coordinates from one geodetic datum into another to serve their desired purpose.

On Affine Transformations of a Riemannian Manifold [PDF]
Nagoya Mathematical Journal, 1955 In this paper we establish some theorems about the group of affine transformations on a Riemannian manifold. First we prove a decomposition theorem (Theorem 1) of the largest connected group of affine transformations on a simply connected complete Riemannian manifold, which corresponds to the decomposition theorem of de Rham [4] for the manifold.

On the Group of Affine Transformations of an Affinely Connected Manifold [PDF]
Proceedings of the American Mathematical Society, 1953 It has been proved by S. Myers and N. Steenrod that the group of all isometries of a Riemannian manifold is a Lie group.2 The purpose of the present note is to establish a similar theorem f6r the group of all affine transformations of an affinely connected manifold under the assumption of "completeness" which will be explained below.
