Eye movement parameters for performance evaluation in projection-based stereoscopic display

Journal of Eye Movement Research, 2018
The current study applied Structural Equation Modeling (SEM) to analyze the relationship among index of difficulty (ID) and parallax on eye movement time (EMT), fixation duration (FD), time to first fixation (TFF), number of fixation (NF), and eye gaze ...

Revisiting Second Wave Feminism in the Light of Recent Controversies

Identities, 2020
This paper revisits elements of second wave feminism—in its psychoanalytic, radical, materialist, Marxist and deconstructionist aspects—the better to understand how it is we might define sexual difference today.

Plant Leaf Position Estimation with Computer Vision

Sensors, 2020
Autonomous analysis of plants, such as for phenotyping and health monitoring etc., often requires the reliable identification and localization of single leaves, a task complicated by their complex and variable shape. Robotic sensor platforms commonly use

An application of Galactic parallax: the distance to the tidal stream GD-1

, 2009
We assess the practicality of computing the distance to stellar streams in our Galaxy, using the method of Galactic parallax suggested by Eyre & Binney (2009).

Quasars can be used to verify the parallax zero-point of the Tycho-Gaia Astrometric Solution

, 2015
Context. The Gaia project will determine positions, proper motions, and parallaxes for more than one billion stars in our Galaxy. It is known that Gaia's two telescopes are affected by a small but significant variation of the basic angle between them ...

Automatic Fine Co-Registration of Datasets from Extremely High Resolution Satellite Multispectral Scanners by Means of Injection of Residues of Multivariate Regression

Remote Sensing
This work presents two pre-processing patches to automatically correct the residual local misalignment of datasets acquired by very/extremely high resolution (VHR/EHR) satellite multispectral (MS) scanners, one for, e.g., GeoEye-1 and Pléiades, featuring

As-Aligned-As-Possible Image Stitching Based on Deviation-Corrected Warping With Global Similarity Constraints

IEEE Access, 2019
Handling local misalignment caused by the local warp remains a common and challenging task for image stitching. Moreover, the stitched image is prone to appearing ghosting due to the variations of the image viewpoint between images.
