Spatially varying image based lighting by light probe sequences
The Visual Computer, 2007 We present a novel technique for capturing spatially or temporally resolved light probe sequences, and using them for image based lighting. For this purpose we have designed and built a real-time light probe, a catadioptric imaging system that can capture the full dynamic range of the lighting incident at each point in space at video frame rates, while

Spatially varying image based lighting using HDR-video
Computers & Graphics, 2013 AbstractIllumination is one of the key components in the creation of realistic renderings of scenes containing virtual objects. In this paper, we present a set of novel algorithms and data structures for visualization, processing and rendering with real world lighting conditions captured using High Dynamic Range (HDR) video.

SkyGAN: Realistic Cloud Imagery for Image‐based Lighting [PDF]
Computer Graphics Forum, 2023 AbstractAchieving photorealism when rendering virtual scenes in movies or architecture visualizations often depends on providing a realistic illumination and background. Typically, spherical environment maps serve both as a natural light source from the Sun and the sky, and as a background with clouds and a horizon.

Experimental evaluation of occupancy lighting control based on low-power image-based motion sensor [PDF]
SICE Journal of Control, Measurement, and System Integration, 2021 Occupancy lighting control, which is used to turn lights on/off based on the occupancy state measured by an occupancy sensor, is a popular and effective type of automatic lighting control. This paper clarifies the effectiveness of occupancy control based

Real‐Time Image‐based Lighting of Glints [PDF]
Computer Graphics ForumAbstractImage‐based lighting is a widely used technique to reproduce shading under real‐world lighting conditions, especially in real‐time rendering applications. A particularly challenging scenario involves materials exhibiting a sparkling or glittering appearance, caused by discrete microfacets scattered across their surface.

The correlation of lighting and mood in the workplace: digital image-based research
Journal of Graphic Engineering and DesignMood affects an individual's performance, whether relaxed/tense or alert/fatigued. This article was based on research to study a correlation between the lighting setting with relaxed-tense and alert/fatigued moods in the workplace by observing the ...

Image-Based Hair Capture by Inverse Lighting
, 2002 We introduce an image-based method for modeling a specific subject's hair. The principle of the approach is to study the variations of hair illumination under controlled illumination. The use of a stationary viewpoint and the assumption that the subject is still allows us to work with perfectly registered images: all pixels in an image sequence ...

Real-time image based lighting with streaming HDR-light probe sequences
, 2012 This work presents a framework for shading of virtual objects using high dynamic range (HDR) light probe sequences in real-time. The method is based on using HDR environment map of the scene which is captured in an on-line process by HDR video camera as light probes [32].
