Compositorial ‘Weight’ & ‘Luminance’ [PDF]

Art and Perception, 2017
Compositorial weight might be understood as an operational definition of salience. It is not a psychophysical entity, but holds a key position between psychophysics and aesthetics. Several factors ranging over raw photometric/colorimetric parameters, various kinds of psychophysical contrast, image geometry, even semantic properties are readily shown to

Illuminance Reconstruction of Road Lighting in Urban Areas for Efficient and Healthy Lighting Performance Evaluation

Applied Sciences, 2018
Big lighting data are required for evaluation of lighting performance and impacts on human beings, environment, and ecology for smart urban lighting. However, traditional approaches of measuring road lighting cannot achieve this aim. We propose a rule-of-

Luminous dark matter [PDF]

Physical Review D, 2010
We propose a dark matter model in which the signal in direct detection experiments arises from electromagnetic, not nuclear, energy deposition. This can provide a novel explanation for DAMA while avoiding many direct detection constraints. The dark matter state is taken nearly degenerate with another state.

Improving Measurement Bias of Structural Similarity Index (SSIM) using Absolute Difference Equation

Applications of Modelling and Simulation, 2022
Structural similarity index (SSIM) is a framework for assessing the perceptual quality from an image using the degrading and structural information of an image.

The Synergy of Architectural Lighting with Sustainable City Development—A Case Study

Buildings
Designing the floodlighting of objects in the context of improving the night image of the city is a very complex task, requiring not only a time commitment but also precise analysis and innovative solutions.

Analysis of the Relationship Between Mural Content and Its Illumination: Two Alternative Directions for Design Guidelines

Arts
As part of contemporary urban culture, murals support place making and city identity. While much attention has been paid to their role in activating public space during daylight hours, their presence after dark remains largely unexamined.

Utilizing a Terrestrial Laser Scanner for 3D Luminance Measurement of Indoor Environments

Journal of Imaging, 2021
We aim to present a method to measure 3D luminance point clouds by applying the integrated high dynamic range (HDR) panoramic camera system of a terrestrial laser scanning (TLS) instrument for performing luminance measurements simultaneously with laser ...

Pupil size affects measures of eye position in video eye tracking: implications for recording vergence accuracy

Journal of Eye Movement Research, 2016
Video eye trackers rely on the position of the pupil centre. However, the pupil centre can shift when the pupil size changes. This pupillary artifact is investigated for binocular vergence accuracy (i.e. fixation disparity) in near vision where the pupil

Brightening and Dimming Aftereffects at Low and High Luminance

Vision, 2018
Adaptation to a spatially uniform field that increases or decreases in luminance over time yields a “ramp aftereffect”, whereby a steady, uniform luminance appears to dim or brighten, and an appropriate non-uniform test field appears to move.
