In the underwater environment, the properties of light (intensity and spectrum) change rapidly with depth and water quality. In this article, we have described how and to what extent lighting conditions can influence the development, growth, and survival of zebrafish. Fertilized eggs and the corresponding larvae were exposed to different visible light wavelengths (violet, blue, green, yellow, r...

To judge the quality of a lighting installation is to determine how well it meets context-specific goals in the areas of architecture, economics, and individual wellbeing. The goals for individual well-being are behaviours such as task performance, mood, social behaviour, aesthetic judgements and satisfaction, that occur as a result of internal processes influenced by luminous conditions. These...

Light plays a key role in synchronizing rhythms and setting the phase of early development. However, to date, little is known about the impact of light wavelengths during the ontogeny of the molecular clock and the behavioural rhythmicity. The aim of this research was to determine the effect of light of different wavelengths (white, blue and red) on the onset of locomotor activity and clock gen...

Surface light fields can be used to render the complex reflectance properties of a physical object. One limitation is that they can only represent the fixed lighting conditions of the environment where the model was captured. If a specific lighting condition is desired, then there are two options: either use a combination of physical lights as an approximation, or capture a full 6D surface refl...

Lighting is a fundamental and important process in the 3D animation pipeline. Conventional lighting workflow is time-consuming and labor-intensive. A user must fiddle with a range of unintuitive parameters one by one for a large set of lights continually to achieve the desired effect. LightShop, introduced here, provides the user with an intuitive and interactive interface employing the paradig...

Fifth Light Technology Ltd., based in Oakville, Ontario, Canada, develops centrally controlled, dimmable lighting systems for office, industrial and public buildings. The company’s approach consists of providing the desired lighting level in the right place at the right time while at the same time taking into account the light conditions in the surroundings, the respective energy costs and the ...

A field study was conducted at three clothing stores to validate previous laboratory findings indicating that colored LEDs used as background display lighting could: 1) lower the power demand of accent lighting by up to 50 percent; and 2) provide greater attention capture and visual appeal than current lighting practice. Blue LEDs provided a colored background for window mannequins by illuminat...

Densely-sampled image representations such as the light field or Lumigraph have been effective in enabling photorealistic image synthesis. Unfortunately, lighting interpolation with such representations has not been shown to be possible without the use of accurate 3D geometry and surface reflectance properties. In this paper, we propose an approach to image-based lighting interpolation that is ...

The performance of modern face recognition systems is a function of the dataset on which they are trained. Most datasets are largely biased toward “near-frontal” views with benign lighting conditions, negatively effecting recognition performance on images that do not meet these criteria. The proposed approach demonstrates how a baseline training set can be augmented to increase pose and lightin...
