Detecting New Visual Binaries in Gaia DR3 with Gaia and Two Micron All Sky Survey (2MASS) Photometry. II. Speckle Observations of 16 Low-separation Systems [PDF]

open access: greenThe Astronomical Journal
Here we present speckle observations of 16 low-separation ( s < 30 au) high-probability candidate binaries from the catalog by Medan et al., where secondaries typically lack astrometric solutions in Gaia. From these speckle observations, we find a second

BinVPR: Binary Neural Networks towards Real-Valued for Visual Place Recognition [PDF]

open access: goldSensors
Visual Place Recognition (VPR) aims to determine whether a robot or visual navigation system locates in a previously visited place using visual information. It is an essential technology and challenging problem in computer vision and robotic communities.

Detecting New Visual Binaries in Gaia DR3 with Gaia and Two Micron All Sky Survey (2MASS) Photometry. I. New Candidate Binaries within 200 pc of the Sun

open access: yesThe Astronomical Journal, 2023
We present a method to identify likely visual binaries in Gaia eDR3 that does not rely on parallax or proper motion. This method utilizes the various point-spread function sizes of Two Micron All Sky Survey (2MASS)/Gaia, where at

Generating Method of Visual Word Bag Model Based on Binary Hashing and Space Pyramid [PDF]

open access: yesJisuanji gongcheng, 2016
Constructing visual vocabulary in the Bag of Visual Word(BoVW) model is a critical step,most visual vocabulary is generated by the k-means algorithm or its improved algorithm.Because of the limitation of the k-means algorithm and the complexity and the ...

Visual Orbits and Alignments of Planet-hosting Binary Systems

open access: yesThe Astronomical Journal, 2023
Roughly half of Solar-type planet hosts have stellar companions, so understanding how these binary companions affect the formation and evolution of planets is an important component to understanding planetary systems overall.

Binary Neural Network for Automated Visual Surface Defect Detection

open access: yesSensors, 2021
As is well-known, defects precisely affect the lives and functions of the machines in which they occur, and even cause potentially catastrophic casualties. Therefore, quality assessment before mounting is an indispensable requirement for factories. Apart

Mass Ratio of Single-line Spectroscopic Binaries with Visual Orbits Using Bayesian Inference and Suitable Priors

open access: yesThe Astronomical Journal, 2023
We present orbital elements for 22 single-line binaries, nine of them studied for the first time, determined from a joint spectroscopic and astrometric solution.

“She Started Wearing Men’s Clothing and Acting More Masculine"

open access: yesThe International Journal of Information, Diversity, & Inclusion, 2021
This paper examines two examples of archival visual information with potentially transgender and non-binary representation to interrogate the descriptive challenges latent within such materials. By using gender theory and queer historiography, this paper

CROSS IN YELLOW

open access: yesSur: International Journal on Human Rights, 2021
The “X” on the sidewalk determined the distance between people in the lineups outside a primary healthcare unit in Porto Alegre, Rio Grande do Sul. However, this mark brings to mind the image of a string of yellow crosses as a reminder of the brutal ...
