A spatially dependent correction of Gaia EDR3 parallax zero-point offset based on 0.3 million LAMOST DR8 giant stars [PDF]

open access: yes, 2022
We have studied the zero-point offset of Gaia early Data Release 3 (EDR3) parallaxes based on a sample of 0.3 million giant stars built from the LAMOST data with distance accuracy better than 8.5\%. The official parallax zero-point corrections largely reduce the global offset in the Gaia EDR3 parallaxes: the global parallax offsets are $-$27.9 $\mu$as ...

A multi‐scale analysis of basketball throw in virtual reality for tracking perceptual‐motor expertise

open access: yesScandinavian Journal of Medicine &Science in Sports, Volume 33, Issue 2, Page 178-188, February 2023., 2023
To benefit from virtual reality (VR) as a complementary tool for training, coaches must determine the proper tools and variables for tracking sports performance. We explored the basketball shooting at several scales (basket‐ball, ball‐player, and player systems) by monitoring success‐rate, and ball and body kinematics.

Parallax Theology: Reframing Compensation Theodicy

open access: yesReligions, 2023
The reality of suffering and the existence of natural and moral evils appear to present significant obstacles to the doctrine of God’s omnipotence, omniscience, and omnibenevolence. Theodicy is an attempt to resolve the problem of evil.

EyePACT: eye-based parallax correction on touch-enabled interactive displays [PDF]

open access: yes, 2017
The parallax effect describes the displacement between the perceived and detected touch locations on a touch-enabled surface. Parallax is a key usability challenge for interactive displays, particularly for those that require thick layers of glass ...

Aircraft and Ship Velocity Determination in Sentinel-2 Multispectral Images

open access: yesSensors, 2019
The Sentinel-2 satellites in the Copernicus program provide high resolution multispectral images, which are recorded with temporal offsets up to 2.6 s. Moving aircrafts and ships are therefore observed at different positions due to the multispectral band

Parallax-Robust Surveillance Video Stitching

open access: yesSensors, 2015
This paper presents a parallax-robust video stitching technique for timely synchronized surveillance video. An efficient two-stage video stitching procedure is proposed in this paper to build wide Field-of-View (FOV) videos for surveillance applications.

Narcissus and the Moon: Parallax in Early Modern Images

open access: yesSignata, 2021
This essay develops a comprehensive approach to the study of parallax effects in early modern images, with critical emphasis on painting. Parallax is the apparent displacement of an object relative to a given background, as caused by the movement of the ...

Lutz-Kelker bias in pulsar parallax measurements [PDF]

open access: yes, 2010
Lutz & Kelker showed that parallax measurements are systematically overestimated because they do not properly account for the larger volume of space that is sampled at smaller parallax values.

Will Self’s Parallactic Urban/Land-scapes in Walking to Hollywood

open access: yesÉtudes Britanniques Contemporaines, 2018
This paper addresses the complex relation of identity to site in Walking to Hollywood: Memories Before the Fall. In keeping with the idea of a cityscape rather experienced than observed or depicted from a distance, the analysis of scale, proportions and ...
