Noise provides new insights on contrast sensitivity function. [PDF]
PLoS ONE, 2014 Sensitivity to luminance difference, or contrast sensitivity, is critical for animals to survive in and interact with the external world. The contrast sensitivity function (CSF), which measures visual sensitivity to spatial patterns over a wide range of ...

Learning Fair Representation via Distributional Contrastive Disentanglement [PDF]
arXiv, 2022 Learning fair representation is crucial for achieving fairness or debiasing sensitive information. Most existing works rely on adversarial representation learning to inject some invariance into representation. However, adversarial learning methods are known to suffer from relatively unstable training, and this might harm the balance between fairness ...

Comparing the Shape of Contrast Sensitivity Functions for Normal and Low Vision
Investigative Ophthalmology and Visual Science, 2015 Purpose The contrast sensitivity function (CSF) provides a detailed description of an individual's spatial-pattern detection capability. We tested the hypothesis that the CSFs of people with low vision differ from a “normal” CSF only in their horizontal ...

Patch-Level Contrasting without Patch Correspondence for Accurate and Dense Contrastive Representation Learning [PDF]
arXiv, 2023 We propose ADCLR: A ccurate and D ense Contrastive Representation Learning, a novel self-supervised learning framework for learning accurate and dense vision representation. To extract spatial-sensitive information, ADCLR introduces query patches for contrasting in addition with global contrasting.

Multiple-crystal X-ray topographic characterization of periodically domain-inverted KTiOPO4 crystal [PDF]
, 1995 A periodically domain-inverted KTiOPO4 crystal has been characterized for the first time by multiple-crystal multiple-reflection x-ray topography. The striation contrast within the domain- inverted regions has been revealed in high strain-sensitivity ...
