A power law study of the edge influence on the perceived filling-in brightness magnitude [PDF]
Background Edge plays a special role in spatial perception and as well as in determining the brightness of a surface within borders. The aim of our study was to measure threshold brightness in different levels of edges thickness.

The role of numerical magnitude and order in the illusory perception of size and brightness [PDF]
Processing magnitudes constitutes a common experience across a multiplicity of dimensions, for example when one has to compare sizes, duration, numbers, sound height or loudness.

Magnitude to luminance conversions and visual brightness of the night sky [PDF]
ABSTRACT The visual brightness of the night sky is not a single-valued function of its brightness in other photometric bands, because the transformations between photometric systems depend on the spectral power distribution of the skyglow.

In this paper, we have evaluated the brightness of lightning leaders shown in a digital still image by applying the astronomical magnitude system. In order to analyze the only lightning leaders, these were extracted from the digital still image.

Super-Resolution Parameter Estimation Using Machine Learning-Assisted Spatial Mode Demultiplexing [PDF]
We present the use of a light-weight machine learning (ML) model to estimate the separation and relative brightness of two incoherent light sources below the diffraction limit.

Magnitude of Discomfort caused by High Brightness [PDF]
HITHERTO the greatest care has been taken here in the studies of building efficiency to avoid methods of subjective judgment which depend on assessment of sensation magnitude in terms of numbers. For certain reasons, however, a numerical assessment of the magnitude of the sensation of discomfort due to glare was required.

Changes in the magnitude of simultaneous brightness contrast as a function of extended practice [PDF]
In 35 sessions of 10 trials apiece, each of eight Ss viewed and judged a display which produced simultaneous brightness contrast. All Ss were given an instructional set toward realistic perception. Members of one subgroup were informed as to the magnitude of their judgments; members of another were not.

Current Status of the Liquid-Metal-Jet X-ray Source Technology [PDF]
High-end x-ray diffraction and scattering techniques such as high-resolution XRD, protein crystallography, and SAXS rely heavily on the x-ray source brightness for resolution and exposure time.

Bright electron bunches from a plasma-wakefield accelerator with a steep density down-ramp [PDF]
High-brightness electron bunches drive fundamental research in particle physics and photon science. Key to achieving a high brightness is to have a low transverse emittance, which ensures that the bunch can be tightly focussed.

Brightness induction magnitude declines with increasing distance from the inducing field edge
Brightness induction refers to a class of visual illusions where the perceived intensity of a region of space is influenced by the luminance of surrounding regions. These illusions are significant because they provide insight into the neural organization and processing strategies employed by the visual system. The nature of these processing strategies,
