Feature matching of remote‐sensing images based on bilateral local–global structure consistency
IET Image Processing, 2023 The goal of feature matching is to establish accurate correspondences between feature points in different images depicting the same scene. To address the polymorphism of local structures, the authors propose a mismatch removal method using bilateral ...

Two-Step Affine Transformation Prediction for Visual Object Tracking
IEEE Access, 2021 The main drawback of correlation filter scheme is that it can only predict translation of the object, ignoring the other affine transformations such as rotation, aspect ratio change, and scale change.

nD Quasi-Affine Transformations [PDF]
, 2016 A Quasi-Affine Transformation QAT is a transformation on $$\mathbb Z^n$$ which corresponds to the composition of a rational affine transformation and an integer part function. The aim of this paper is twofold. Firstly, it brings new insight into the periodic structures involved by a QAT. Secondly, some new results in nD are presented specifically about

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 Schwartzman group of an affine transformation
Journal of Spectral Theory, 2023 We compute the Schwartzman group associated with an ergodic affine automorphism of a compact connected abelian group given by the composition of an automorphism of the group and a translation by an element in the path component of the identity. We show that the Schwartzman group can be characterized by evaluating the invariant characters of the ...

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
