Publikováno v: PLoS ONE
PLoS ONE, Vol 15, Iss 12, p e0243237 (2020)

It has recently been demonstrated through invasive electrophysiology that visual stimulation with extended patches of uniform colour generates pronounced gamma oscillations in the visual cortex of both macaques and humans. In this study we sought to

Development and Performance Assessment of White LED Dimmer

Autor: Biswanath Roy, Pradip Maiti

Publikováno v: Journal of The Institution of Engineers (India): Series B. 98:461-466

A microcontroller based electronic dimmer is developed using pulse width modulation technique. This dimmer is controllable by infra-red remote within a distance of 4 m and can be electrically connected between LED module and its driver. The performan

A Fusion Method for Low-Illumination Color Image Enhancement on CIELUV Space

Autor: Chien-Cheng Tseng, Su-Ling Lee

Publikováno v: GCCE

In this paper, a fusion method for low-illumination color image enhancement on CIELUV space is presented. First, the input color image on RGB space is converted into the one on CIELUV space. Then, three color image enhancement methods are employed to

Temporal dynamics of daylight perception: Detection thresholds

Autor: Anya Hurlbert, Naomi Gross, Gaurav Gupta, Ruben Pastilha

Publikováno v: Journal of Vision

Temporal changes in illumination are ubiquitous; natural light, for example, varies in color temperature and irradiance throughout the day. Yet little is known about human sensitivity to temporal changes in illumination spectra. Here, we aimed to det

Joint Retinex-based variational model and CLAHE-in-CIELUV for enhancement of low-quality color retinal images

Autor: Chen Tang, Min Xu, Zongheng Huang, Zhenkun Lei

Publikováno v: Applied Optics. 59:8628

Poor visual quality of color retinal images greatly interferes with the analysis and diagnosis of the ophthalmologist. In this paper, we propose an enhancement method for low-quality color retinal images based on the combination of the Retinex-based

Geometrical structure of perceptual color space: mental representations and adaptation invariance

Autor: Robert Ennis, Qasim Zaidi

Publikováno v: Journal of Vision

A central issue in neuroscience is to understand how the brain builds structured representations of percepts that facilitate useful inferences about the world. Similarity between percepts is used to accomplish many everyday tasks, e.g. object identif
