Abmact-In this correspondence, we show that images that could not have arisen from shading on a smooth surface with uniform reflecting properties and lighting exist. Much work has been done on recovering surface shape from images, and there has been some attention paid to the question of uniqueness. It has been shown, for example, that singular points curtail ambiguity. However, little has been...

Preface The Code of Practice for Energy Efficiency of Lighting Installations (Lighting Code) developed by the Electrical & Mechanical Services Department (EMSD) aims to set out the minimum design requirements on energy efficiency of lighting installations. It forms a part of a set of comprehensive Building Energy Codes (BEC) that addresses energy efficiency requirements in building services ins...

Lighting estimation from face images is an important task and has applications in many areas such as image editing, intrinsic image decomposition, and image forgery detection. We propose to train a deep Convolutional Neural Network (CNN) to regress lighting parameters from a single face image. Lacking massive ground truth lighting labels for face images in the wild, we use an existing method to...

This paper focuses on lighting dimensioning and lighting quality of traffic lighting. The work considers the factors that are important in creating optimal lighting conditions and luminous environment for night-time driving. The work is based on simulating, measuring and analyzing traffic lighting. The work introduces a new method for road luminance measurements and analysis. For simulation of ...

The goal of this study was to examine how different light combinations and timing of supplemental lighting affect the vegetative and reproductive responses of pansy (Viola × wittrockiana Rose). The present study was designed as a factorial experiment based on a completely randomized block design with three replications and two factors of timing of supplemental lighting (night-interrupt...

We investigate how lighting can be used to influence how the personality of virtual characters is perceived. We propose a character-centric lighting system composed of three dynamic lights that can be configured using an interactive editor. To study the effect of character-centric lighting on observers, we created four lighting configurations derived from the photography and film literature. A ...
