The Cepheid period -- luminosity -- metallicity relation based on Gaia DR2 data

open access: yes, 2018
We use parallax data from the Gaia second data release (GDR2), combined with parallax data based on Hipparcos and HST data, to derive the period-luminosity-metallicity (PLZ) relation for Galactic classical cepheids (CCs) in the V,K, and Wesenheit WVK ...

Verification of Photometric Parallaxes with Gaia DR2 Data

open access: yesGalaxies, 2018
Results of comparison of Gaia DR2 parallaxes with data derived from a combined analysis of 2MASS (Two Micron All-Sky Survey), SDSS (Sloan Digital Sky Survey), GALEX (Galaxy Evolution Explorer), and UKIDSS (UKIRT Infrared Deep Sky Survey) surveys in four ...

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

open access: yesIEEE 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.

Leadership Multiplicities Before and During the Post-Truth Era

open access: yesAdministrative Sciences, 2018
Drawing from the ontology of the lack (Laclau and Mouffe 1985), aesthetic theory (Adorno 1997); practice theory (Bourdieu 2002), art perception theory (Bourdieu 1968), and storytelling theory (Boje 2001), we discuss leadership multiplicities and post ...

Active Estimation of Distance in a Robotic Vision System that Replicates Human Eye Movement [PDF]

open access: yes, 2005
Many visual cues, both binocular and monocular, provide 3D information. When an agent moves with respect to a scene, an important cue is the different motion of objects located at various distances.

Comparative Evaluation of Radiographic Techniques for the Localization of Impacted Maxillary Canine

open access: yesJournal of Indian Academy of Oral Medicine and Radiology, 2006
The maxillary canine being the last anterior tooth to erupt in the oral cavity, is commonly impacted and the reasons for which are multifocal. It is necessary to locate the position of the impacted tooth in order to carry out a proper treatment plan ...

Relative Importance of Binocular Disparity and Motion Parallax for Depth Estimation: A Computer Vision Approach

open access: yesRemote Sensing, 2019
Binocular disparity and motion parallax are the most important cues for depth estimation in human and computer vision. Here, we present an experimental study to evaluate the accuracy of these two cues in depth estimation to stationary objects in a static
