DATENeRF: Depth-Aware Text-based Editing of NeRFs

no code implementations6 Apr 2024 Sara Rojas, Julien Philip, Kai Zhang, Sai Bi, Fujun Luan, Bernard Ghanem, Kalyan Sunkavall

However, extending these techniques to edit scenes in Neural Radiance Fields (NeRF) is complex, as editing individual 2D frames can result in inconsistencies across multiple views.

LightIt: Illumination Modeling and Control for Diffusion Models

no code implementations15 Mar 2024 Peter Kocsis, Julien Philip, Kalyan Sunkavalli, Matthias Nießner, Yannick Hold-Geoffroy

Our method is the first that enables the generation of images with controllable, consistent lighting and performs on par with specialized relighting state-of-the-art methods.

Materialistic: Selecting Similar Materials in Images

no code implementations22 May 2023 Prafull Sharma, Julien Philip, Michaël Gharbi, William T. Freeman, Fredo Durand, Valentin Deschaintre

We present a method capable of selecting the regions of a photograph exhibiting the same material as an artist-chosen area.

JoIN: Joint GANs Inversion for Intrinsic Image Decomposition

no code implementations18 May 2023 Viraj Shah, Svetlana Lazebnik, Julien Philip

In this work, we propose to solve ill-posed inverse imaging problems using a bank of Generative Adversarial Networks (GAN) as a prior and apply our method to the case of Intrinsic Image Decomposition for faces and materials.

Floaters No More: Radiance Field Gradient Scaling for Improved Near-Camera Training

1 code implementation4 May 2023 Julien Philip, Valentin Deschaintre

NeRF acquisition typically requires careful choice of near planes for the different cameras or suffers from background collapse, creating floating artifacts on the edges of the captured scene.

PixHt-Lab: Pixel Height Based Light Effect Generation for Image Compositing

no code implementations CVPR 2023 Yichen Sheng, Jianming Zhang, Julien Philip, Yannick Hold-Geoffroy, Xin Sun, He Zhang, Lu Ling, Bedrich Benes

To compensate for the lack of geometry in 2D Image compositing, recent deep learning-based approaches introduced a pixel height representation to generate soft shadows and reflections.

Point-NeRF: Point-based Neural Radiance Fields

1 code implementation CVPR 2022 Qiangeng Xu, Zexiang Xu, Julien Philip, Sai Bi, Zhixin Shu, Kalyan Sunkavalli, Ulrich Neumann

Point-NeRF combines the advantages of these two approaches by using neural 3D point clouds, with associated neural features, to model a radiance field.

Free-viewpoint Indoor Neural Relighting from Multi-view Stereo

no code implementations24 Jun 2021 Julien Philip, Sébastien Morgenthaler, Michaël Gharbi, George Drettakis

We design a convolutional network around input feature maps that facilitate learning of an implicit representation of scene materials and illumination, enabling both relighting and free-viewpoint navigation.

Deep Blending for Free-Viewpoint Image-Based-Rendering

1 code implementation SIGGRAPH Asia 2018 2018 Peter Hedman, Julien Philip, True Price, Jan-Michael Frahm, George Drettakis, Gabriel Brostow

We present a new deep learning approach to blending for IBR, in which we use held-out real image data to learn blending weights to combine input photo contributions.
