Edges and gradients in lightness illusions: Role of optical veiling glare

open access: yesFrontiers in Psychology, 2022
Lightness Illusions (Contrast, Assimilation, and Natural Scenes with Edges and Gradients) show that appearances do not correlate with the light sent from the scene to the eye.

The switching glare illusion: Appearance and disappearance of glare effect due to figure-ground reversal

open access: yesi-Perception, 2023
The glare illusion is an illusory perception of brightness enhancement and self-luminosity from a glare pattern, which consists of a central white area and surrounding areas with radial darkening luminance gradients. Here, we report a phenomenon we call “

Anisotropy in the peripheral visual field based on pupil response to the glare illusion

open access: yesHeliyon, 2022
Visual-field (VF) anisotropy has been investigated in terms of spatial resolution of attention, spatial frequency, and semantic processing. Brightness perception has also been reported to vary between VFs.

Auditory discomfort in visually sensitive individuals

open access: yesFrontiers in Psychology, 2023
IntroductionSensory discomfort occurs in clinical and non-clinical populations. While some of the parameters that evoke visual discomfort have been identified, the parameters of sounds that evoke auditory discomfort are largely unknown.MethodsWe ...

Veiling glare removal: synthetic dataset generation, metrics and neural network architecture

open access: yesКомпьютерная оптика, 2021
In photography, the presence of a bright light source often reduces the quality and readability of the resulting image. Light rays reflect and bounce off camera elements, sensor or diaphragm causing unwanted artifacts. These artifacts are generally known

Attenuated alpha oscillation and hyperresponsiveness reveals impaired perceptual learning in migraineurs

open access: yesThe Journal of Headache and Pain, 2022
Background Anomalous phantom visual perceptions coupled to an aversion and discomfort to some visual patterns (especially grating in mid-range spatial frequency) have been associated with the hyperresponsiveness in migraine patients.

Pattern-Related Visual Stress, Chromaticity, and Accommodation [PDF]

open access: yes, 2010
PURPOSE. To investigate the impact of colored overlays on the accommodative response of individuals, with and without pattern- related visual stress (PRVS), a condition in which individuals manifest symptoms of perceptual distortion and discomfort when ...

Visual stress, its treatment with spectral filters, and its relationship to visually induced motion sickness [PDF]

open access: yes, 2009
We review the concept of visual stress and its relation to neurological disease. Visual stress can occur from the observation of images with unnatural spatial structure and an excess of contrast energy at spatial frequencies to which the visual system is
