IBL-NeRF: Image-Based Lighting Formulation of Neural Radiance Fields [PDF]
Computer graphics forum (Print), 2022 We propose IBL‐NeRF, which decomposes the neural radiance fields (NeRF) of large‐scale indoor scenes into intrinsic components. Recent approaches further decompose the baked radiance of the implicit volume into intrinsic components such that one can ...

DiLightNet: Fine-grained Lighting Control for Diffusion-based Image Generation [PDF]
International Conference on Computer Graphics and Interactive TechniquesThis paper presents a novel method for exerting fine-grained lighting control during text-driven diffusion-based image generation. While existing diffusion models already have the ability to generate images under any lighting condition, without ...

Spectral Super-Resolution for High Dynamic Range Images
Journal of Imaging, 2023 The images we commonly use are RGB images that contain three pieces of information: red, green, and blue. On the other hand, hyperspectral (HS) images retain wavelength information.

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 ...

Image Relighting Network Based on Context-gated Residuals and Multi-scale Attention [PDF]
Jisuanji kexue, 2023 Image relighting is commonly used in image editing and data augmentation tasks.Existing image relighting methods suffer from estimating accurate shadows and obtaining consistent structures and clear texture when removing and rendering sha-dows in complex

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.
