Compact Optical Visual Magnification System with a Wide Field of View [PDF]
SensorsA new concept for designing a visual magnification system is introduced. In this concept, apart from the conventional objective and the eyepiece group lenses in the system, an additional Power-Corrector (PC) group of lenses is introduced in the optical ...

Useful Field of View Test [PDF]
Gerontology, 2014 The useful field of view test was developed to reflect the visual difficulties that older adults experience with everyday tasks. Importantly, the useful field of view test (UFOV) is one of the most extensively researched and promising predictor tests for a range of driving outcomes measures, including driving ability and crash risk as well as other ...

The Maximum Cover with Rotating Field of View
Journal of Mathematical Imaging and Vision, 2023 Abstract In this paper, we address the maximum cover problem of a rotating field of view (FOV) with a convex polygon $$\mathcal {P}$$ P with n vertices. The problem is defined as determining the optimal rotation angle

Three Dimensional Nonlinear Guidance Law for Exact Impact Time Control
IEEE Access, 2022 This paper presents a nonlinear guidance law for controlling the impact time of a missile-target engagement in three dimensions. The guidance law is initially formulated for a two-dimensional encounter before being extended to a three-dimensional ...

Mapping Burned Areas in Tropical Forests Using a Novel Machine Learning Framework
Remote Sensing, 2018 This paper presents an application of a novel machine-learning framework on MODIS (moderate-resolution imaging spectroradiometer) data to map burned areas over tropical forests of South America and South-east Asia.

Anisotropic Field-of-Views in Radial Imaging [PDF]
IEEE Transactions on Medical Imaging, 2008 Radial imaging techniques, such as projection-reconstruction (PR), are used in magnetic resonance imaging (MRI) for dynamic imaging, angiography, and short-imaging. They are robust to flow and motion, have diffuse aliasing patterns, and support short readouts and echo times. One drawback is that standard implementations do not support anisotropic field-

Gap Affordance Judgments in Mixed Reality: Testing the Role of Display Weight and Field of View
Frontiers in Virtual Reality, 2021 Measures of perceived affordances—judgments of action capabilities—are an objective way to assess whether users perceive mediated environments similarly to the real world.
