Visual Binary Stars with Partially Missing Data: Introducing Multiple Imputation in Astrometric Analysis [PDF]
Publications of the Astronomical Society of the Pacific, 2019 Partial measurements of relative position are a relatively common event during the observation of visual binary stars. However, these observations are typically discarded when estimating the orbit of a visual pair.

Binary Neural Network for Automated Visual Surface Defect Detection
Sensors, 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

Attention Convolutional Binary Neural Tree for Fine-Grained Visual Categorization [PDF]
Computer Vision and Pattern Recognition, 2019 Fine-grained visual categorization (FGVC) is an important but challenging task due to high intra-class variances and low inter-class variances caused by deformation, occlusion, illumination, etc. An attention convolutional binary neural tree architecture

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

Binary image steganography method based on layered embedding
网络与信息安全学报, 2021 A non-additive distortion binary image steganography method was proposed which divided the cover image into two sub cover images, updated the distortion through delivering influence factor, and used the minimizing distortion codes to achieve message ...

The same, but different: Stochasticity in binary destruction [PDF]
, 2012 Observations of binaries in clusters tend to be of visual binaries with separations of 10s - 100s au. Such binaries are 'intermediates' and their destruction or survival depends on the exact details of their individual dynamical history.

Sur: 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 ...

Binary Artificial Immune Algorithm for Adaptive Visual Detection
IEEE Access, 2018 A visual model plays an important role in developing an efficient and robust visual tracker. The visual cues employed in the state-of-the-art models are usually predefined and fixed for all the tested videos.
