nD Quasi-Affine Transformations [PDF]
, 2016 A Quasi-Affine Transformation (QAT) is a transformation on $\mathbb Z^n$ which corresponds to the composition of an affine transformation and an integer part function. The author of this report and other authors (Coeurjolly, Tellier, Nehlig...) have already studied QATs and their applications.

Adaptive enhanced affine transformation for non‐rigid registration of visible and infrared images [PDF]
IET Image Processing, 2021 Non‐rigid registration, performing well in all‐weather and all‐day/night conditions, directly determine the reliability of visible (VIS) and infrared (IR) image fusion.

Robust Object Tracking Using Affine Transformation and Convolutional Features
IEEE Access, 2019 The state-of-the-art trackers using deep learning technology have no special strategy to capture the geometric deformation of the target. Based on that the affine manifold can better capture the target shape change and that the higher level of ...

A three-step, “brute-force” approach toward optimized affine spatial normalization [PDF]
Frontiers in Computational NeuroscienceThe first step in spatial normalization of magnetic resonance (MR) images commonly is an affine transformation, which may be vulnerable to image imperfections (such as inhomogeneities or “unusual” heads).

Recurrent Affine Transformation for Text-to-Image Synthesis [PDF]
IEEE transactions on multimedia, 2022 Text-to-image synthesis aims to generate realistic images conditioned on text descriptions. Recently, conditional affine transformations (CATs), such as conditional batch normalization and instance normalization, have been applied to different layers to ...

SemAffiNet: Semantic-Affine Transformation for Point Cloud Segmentation [PDF]
Computer Vision and Pattern Recognition, 2022 Conventional point cloud semantic segmentation methods usually employ an encoder-decoder architecture, where mid-level features are locally aggregated to extract geometric information.

Safe Affine Transformation-Based Guidance of a Large-Scale Multiquadcopter System [PDF]
IEEE Transactions on Control of Network Systems, 2021 This article studies the problem of affine transformation-based guidance of a multiquadcopter system (MQS) in an obstacle-laden environment. Such MQSs can perform a variety of cooperative tasks including information collection, inspection mapping ...

Affine transformations of the tangent bundle of a common path space
Дифференциальная геометрия многообразий фигур, 2023 In this paper, we study infinitesimal transformations of the tangent bundle of a common path space. The general path space is a generalization space of the affine connectivity.

Reversibility of affine transformations
Proceedings of the Edinburgh Mathematical Society, 2023 AbstractAn element g in a group G is called reversible if g is conjugate to g−1 in G. An element g in G is strongly reversible if g is conjugate to g−1 by an involution in G. The group of affine transformations of $\mathbb D^n$ may be identified with the semi-direct product $\mathrm{GL}(n, \mathbb D) \ltimes \mathbb D^n $, where $\mathbb D:=\mathbb R, \
