Lighting plays a key role in night escapes of urban spaces, in a way that it can be effective in giving identity to them. By considering this importance and inexistence of a process for composing urban Lighting strategy made this study to be conducted by the objective of providing process for compilation of context-oriented lighting strategy in urban spaces. Reaching a suitable solution for Li...

it is accepted that the visual comfort in schools depends on the quality of the whole visual environment. this leads to the concern upon the quality and quantity of lighting. currently in iran, in order to calculate energy transfer for public buildings a coefficient is usually used. this coefficient considers the rate of sunlight energy absorption in these kinds of buildings. to increase the de...

Appearance-based place recognition systems have been shown to be effective for large-scale mapping but have notable shortcomings. Visual bag-of-words dictionaries require offline training, have tens of thousands of words, and are susceptible to changing environments, either due to lighting or physical changes, between training and deployment. Recent advances allow for online 3D mapping and segm...

1. Much concern has been expressed about the ecological consequences of night-time light pollution. This concern is most often focused on the encroachment of artificial light into previously unlit areas of the night-time environment, but changes in the spectral composition, duration and spatial pattern of light are also recognized as having ecological effects.2. Here, we examine the potential c...

Artificial light is globally one of the most widely distributed forms of anthropogenic pollution. However, while both the nature and ecological effects of direct artificial lighting are increasingly well documented, those of artificial sky glow have received little attention.We investigated how city lights alter natural regimes of lunar sky brightness using a novel ten month time series of meas...

Modeling and visualization of natural and realistic outdoor ecosystems like forests or meadows remains a highly challenging task in computer graphics. Convincing and non-artificial scenes require many thousands to millions of plants, each modeled with a high degree of geometric, shading, and lighting detail. At the same time many applications demand interactive rendering at high fidelity. In th...

One approach to detect spliced images is to compare the lighting environment of suspicious objects or persons in the scene. The original method, proposed by Johnson and Farid, requires an investigator to mark occluding contours of multiple objects, from which the distribution of the incident light intensity is estimated. Unfortunately, this method imposes relatively strict constraints on the us...

CODYRUN is a multi-zone software integrating thermal building simulation, airflow, and pollutant transfer. A first question thus arose as to the integration of indoor lighting conditions into the simulation, leading to a new model calculating natural and artificial lighting. The results of this new daylighting module were then compared with results of other simulation codes and experimental cas...

A challenge in presenting augmenting information in outdoor augmented reality (AR) settings lies in the broad range of uncontrollable environmental conditions that may be present, specifically large-scale fluctuations in natural lighting and wide variations in likely backgrounds or objects in the scene. In this paper, we motivate the need for research on the effects of text drawing styles, outd...
