Image based relighting using room lighting basis [PDF]
ACM SIGGRAPH 2015 Posters, 2015 We present a novel and practical approach for image-based relighting that employs the lights available in a regular room to acquire the reflectance field of an object. The lighting basis includes diverse light sources such as the house lights and the natural illumination coming from the windows.

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.

Physically-Based Editing of Indoor Scene Lighting from a Single Image [PDF]
European Conference on Computer Vision, 2022 We present a method to edit complex indoor lighting from a single image with its predicted depth and light source segmentation masks. This is an extremely challenging problem that requires modeling complex light transport, and disentangling HDR lighting ...

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
