Visualizing the third dimension in virtual training environments for neurologically impaired persons: beneficial or disruptive?

Journal of NeuroEngineering and Rehabilitation, 2012
Background Many contemporary systems for neurorehabilitation utilize 3D virtual environments (VEs) that allow for training patients’ hand or arm movements.

A Benchmark Evaluation of Adaptive Image Compression for Multi Picture Object Stereoscopic Images

Journal of Imaging, 2021
A stereopair consists of two pictures related to the same subject taken by two different points of view. Since the two images contain a high amount of redundant information, new compression approaches and data formats are continuously proposed, which aim

Adaptable 2D to 3D Stereo Vision Image Conversion Based on a Deep Convolutional Neural Network and Fast Inpaint Algorithm

Entropy, 2023
Algorithms for converting 2D to 3D are gaining importance following the hiatus brought about by the discontinuation of 3D TV production; this is due to the high availability and popularity of virtual reality systems that use stereo vision. In this paper,

Fixing an illusion – an empirical assessment of correction methods for the terrain reversal effect in satellite images

International Journal of Digital Earth, 2020
Identifying land forms and land cover classes are important tasks in image interpretation. Sometimes, a phenomenon called terrain reversal effect (TRE) causes an inverted perception of 3D forms.

Meta‐Virtuality: Strategies of Disembeddedness in Virtual Interiorities

Journal of Interior Design, EarlyView., 2022
ABSTRACT To reclaim their seat in the rapidly growing market of virtual space, designers of the built environment can benefit from reevaluating theories that see the virtual as a mere extension/reflection of the physical. By claiming ontological autonomy from external worlds, the virtual is liberated from the hegemonic control of the physical.

Three-Dimensional Reconstruction of Individual Particles in Dense Dust Clouds: Benchmarking Camera Orientations and Reconstruction Algorithms

Journal of Imaging, 2019
In dusty plasmas, determining the three-dimensional particle positions and trajectories of individual particles is often required. This paper benchmarks two approaches capable of reconstructing the trajectories of particles in three dimensions.

Contact Lens with Moiré Patterns for High‐Precision Eye Tracking

Advanced Functional Materials, EarlyView.
This work presents a passive contact lens for high‐precision eye tracking, integrating a microscopic moiré grating label. The parallax‐induced shift of macroscopic moiré patterns enables angle measurement with 0.28° precision using a standard camera under ambient light.
