Extracting Triangular 3D Models, Materials, and Lighting From Images [PDF]
Computer Vision and Pattern Recognition, 2021 We present an efficient method for joint optimization of topology, materials and lighting from multi-view image observations. Unlike recent multi-view reconstruction approaches, which typically produce entangled 3D representations encoded in neural ...

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 ...

Learning Indoor Inverse Rendering with 3D Spatially-Varying Lighting [PDF]
IEEE International Conference on Computer Vision, 2021 In this work, we address the problem of jointly estimating albedo, normals, depth and 3D spatially-varying lighting from a single image. Most existing methods formulate the task as image-to-image translation, ignoring the 3D properties of the scene ...
