ReDet: A Rotation-equivariant Detector for Aerial Object Detection [PDF]
Computer Vision and Pattern Recognition, 2021 Recently, object detection in aerial images has gained much attention in computer vision. Different from objects in natural images, aerial objects are often distributed with arbitrary orientation.

Real-Time Kinematic Imagery-Based Automated Levelness Assessment System for Land Leveling
Agriculture, 2023 Many cropping systems, notably for rice or soybean production, rely largely on arable land levelness. In this study, an automated levelness assessment system (ALAS) for evaluating lowland levelness is proposed.

Journal of the London Mathematical Society, 2023 AbstractWe describe the infinite interval exchange transformations, called the rotated odometers, which are obtained as compositions of finite interval exchange transformations and the von Neumann–Kakutani map. We show that with respect to Lebesgue measure on the unit interval, every such transformation is measurably isomorphic to the first return map ...

On the Continuity of Rotation Representations in Neural Networks [PDF]
Computer Vision and Pattern Recognition, 2018 In neural networks, it is often desirable to work with various representations of the same space. For example, 3D rotations can be represented with quaternions or Euler angles.

Arbitrary-Oriented Scene Text Detection via Rotation Proposals [PDF]
IEEE transactions on multimedia, 2017 This paper introduces a novel rotation-based framework for arbitrary-oriented text detection in natural scene images. We present the Rotation Region Proposal Networks, which are designed to generate inclined proposals with text orientation angle ...

Mathematical Methods in the Applied Sciences, 2021 Many problems in computer vision today are solved via deep learning. Tasks like pose estimation from images, pose estimation from point clouds or structure from motion can all be formulated as a regression on rotations. However, there is no unique way of parametrizing rotations mathematically: matrices, quaternions, axis-angle representation or Euler ...

Rotational autokeratoplasty [PDF]
Eye, 1989 The results of sixteen patients who had undergone ipsilateral rotational autokeratoplasty are presented. Thirteen patients obtained significant visual improvement, and eight patients achieved an acuity of 6/12 or better. There were no significant pre-operative or post-operative complications.

Rotation-Sensitive Regression for Oriented Scene Text Detection [PDF]
2018 IEEE/CVF Conference on Computer Vision and Pattern Recognition, 2018 Text in natural images is of arbitrary orientations, requiring detection in terms of oriented bounding boxes. Normally, a multi-oriented text detector often involves two key tasks: 1) text presence detection, which is a classification problem ...
