Unsupervised Deep Hashing for Large-scale Visual Search [PDF]
, 2016 Learning based hashing plays a pivotal role in large-scale visual search. However, most existing hashing algorithms tend to learn shallow models that do not seek representative binary codes.

The attentional drift-diffusion model extends to simple purchasing decisions [PDF]
, 2012 How do we make simple purchasing decisions (e.g., whether or not to buy a product at a given price)? Previous work has shown that the attentional drift-diffusion model (aDDM) can provide accurate quantitative descriptions of the psychometric data for ...

Coding local and global binary visual features extracted from video sequences [PDF]
, 2015 Binary local features represent an effective alternative to real-valued descriptors, leading to comparable results for many visual analysis tasks, while being characterized by significantly lower computational complexity and memory requirements.

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.

Accurate M Dwarf Metallicities from Spectral Synthesis: A Critical Test of Model Atmospheres [PDF]
, 2006 We describe a method for accurately determining M dwarf metallicities with spectral synthesis based on abundance analyses of visual binary stars. We obtained high resolution, high signal-to-noise spectra of each component of five visual binary pairs at ...

Some spectroscopic observations of visual binaries [PDF]
Astrophysics and Space Science, 1965 AbstractThe use of a coudé spectrograph for securing the high-resolution spectrograms necessary to follow the slow variations of radial velocity exhibited by visual binaries is discussed. Recent observations, using the spectrograph at the coudé focus of the Dominion Astrophysical Observatory’s 48-in. reflector, are then presented for the systems ofαUMa,
