A Brücke–Bartley effect for contrast [PDF]
Accurate derivation of the psychophysical (a.k.a. transducer) function from just-notable differences requires accurate knowledge of the relationship between the mean and variance of apparent intensities.

Image Quality for Near-Eye Display Based on Holographic Waveguides
The paper analyzes the image quality in augmented reality display based on holographic waveguides. Brightness, brightness non-uniformity, image noise, etc., depend on the parameters of the waveguide substrate, the configuration, and the relief shape of ...

the size of the burden of unmet needs of older people living in the community is unknown. We aim to validate a brief postal questionnaire, the Brief Risk Identification of Geriatric Health Tool (BRIGHT) questionnaire, to find cases of older people with disabilities (case-finding) living in the community.community-dwelling patients over the age of 75 ...

The perception of brightness depends on spatial context: the same stimulus can appear light or dark depending on what surrounds it. A less well-known but equally important contextual phenomenon is that the colour of a stimulus can also alter its brightness. Specifically, stimuli that are more saturated (i.e.
