Cross-modal commutativity of magnitude productions of loudness and brightness [PDF]
Attention, Perception, & Psychophysics, 2021 AbstractIn their fundamental paper, Luce, Steingrimsson, and Narens (2010, Psychological Review, 117, 1247-1258) proposed that ratio productions constituting a generalization of cross-modality matching may be represented on a single scale of subjective intensity, if they meet “cross-dimensional commutativity.” The present experiment is the first to ...

Frontiers in Human Neuroscience, 2023 The brightness (perceived intensity) of a region of visual space depends on its luminance and on the luminance of nearby regions. This phenomenon is called brightness induction and includes both brightness contrast and assimilation.

Theoretical formulation and experimental validation of brightness evaluation using digital cameras
Results in Optics, 2021 In this study, we formulated the brightness relation of two digital photos captured by a single digital camera and verified it experimentally. The experimental results suggested that the used zoom lens has an intrinsic error, thereby making accurate ...

Modelling the Microphone-Related Timbral Brightness of Recorded Signals
Applied Sciences, 2021 Brightness is one of the most common timbral descriptors used for searching audio databases, and is also the timbral attribute of recorded sound that is most affected by microphone choice, making a brightness prediction model desirable for automatic ...

The surface brightness and colour-magnitude relations for Fornax cluster galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2003 We present BVI photometry of 190 galaxies in the central region of the Fornax Cluster observed with the Michigan Curtis Schmidt Telescope. The cluster members exhibit a strong surface brightness-magnitude relation in our data: both giant and dwarf ellipticals decrease in surface brightness as luminosity decreases.
