GEOMETRIC STITCHING METHOD FOR DOUBLE CAMERAS WITH WEAK CONVERGENCE GEOMETRY [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017
In this paper, a new geometric stitching method is proposed which utilizes digital elevation model (DEM)-aided block adjustment to solve relative orientation parameters for dual-camera with weak convergence geometry. A rational function model (RFM) with

Using Rational Polynomial Coefficients (RPC) to generate digital elevation models : a comparative study

, 2016
Models based on Rational Polynomial Coefficients (RPC) have recently sparked considerable interest within the remote sensing community because of their simplicity and accuracy.

AUTOMATIC REGISTRATION OF GF4 PMS: A HIGH RESOLUTION MULTI-SPECTRAL SENSOR ON BOARD A SATELLITE ON GEOSTATIONARY ORBIT [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
Geometric correction is an important preprocessing process in the application of GF4 PMS image. The method of geometric correction that is based on the manual selection of geometric control points is time-consuming and laborious.

Orthogonal rational functions with real coefficients and semiseparable matrices [PDF]

, 2010
When one wants to use Orthogonal Rational Functions (ORFs) in system identification or control theory, it is important to be able to avoid complex calculations. In this paper we study ORFs whose numerator and denominator polynomial have real coefficients.

Linear Optimization of Polynomial Rational Functions: Applications for Positivity Analysis

Mathematics, 2020
In this paper, we provide tight linear lower bounding functions for multivariate polynomials given over boxes. These functions are obtained by the expansion of polynomials into Bernstein basis and using the linear least squares function.

Lattice-points enumeration in polytopes: study of the coefficients of the Ehrhart quasi-polynomial

, 2016
A very important problem in discrete geometry is counting points with integer-coordinates (also called "lattice-points") in polytopes. A polytope is a geometric shape that is the smallest convex set containing the vertices defining the polytope.

Center point matching network based on multi-coverage templates for high-resolution satellite orthorectification

KSCE Journal of Civil Engineering
High-resolution (HR) satellite images are provided with rational polynomial coefficients (RPCs) that map ground coordinates to image space. However, initial RPCs are derived from approximate models and contain geometric errors.

Jacobi–Sobolev Orthogonal Polynomials, Differential Properties and Structural Formulas

Axioms
In this paper, we extend some differential and structural results for monic Jacobi–Sobolev orthogonal polynomials, associated with a general discrete Sobolev inner product, with a Jacobi continuous part. We consider finitely many exterior mass points and
