WildFusion: Learning 3D-Aware Latent Diffusion Models in View Space

no code implementations22 Nov 2023 Katja Schwarz, Seung Wook Kim, Jun Gao, Sanja Fidler, Andreas Geiger, Karsten Kreis

Then, we train a diffusion model in the 3D-aware latent space, thereby enabling synthesis of high-quality 3D-consistent image samples, outperforming recent state-of-the-art GAN-based methods.

NeuralField-LDM: Scene Generation with Hierarchical Latent Diffusion Models

no code implementations CVPR 2023 Seung Wook Kim, Bradley Brown, Kangxue Yin, Karsten Kreis, Katja Schwarz, Daiqing Li, Robin Rombach, Antonio Torralba, Sanja Fidler

We first train a scene auto-encoder to express a set of image and pose pairs as a neural field, represented as density and feature voxel grids that can be projected to produce novel views of the scene.

ARAH: Animatable Volume Rendering of Articulated Human SDFs

no code implementations18 Oct 2022 Shaofei Wang, Katja Schwarz, Andreas Geiger, Siyu Tang

We demonstrate that our proposed pipeline can generate clothed avatars with high-quality pose-dependent geometry and appearance from a sparse set of multi-view RGB videos.

VoxGRAF: Fast 3D-Aware Image Synthesis with Sparse Voxel Grids

1 code implementation15 Jun 2022 Katja Schwarz, Axel Sauer, Michael Niemeyer, Yiyi Liao, Andreas Geiger

State-of-the-art 3D-aware generative models rely on coordinate-based MLPs to parameterize 3D radiance fields.

StyleGAN-XL: Scaling StyleGAN to Large Diverse Datasets

2 code implementations1 Feb 2022 Axel Sauer, Katja Schwarz, Andreas Geiger

StyleGAN in particular sets new standards for generative modeling regarding image quality and controllability.

On the Frequency Bias of Generative Models

1 code implementation NeurIPS 2021 Katja Schwarz, Yiyi Liao, Andreas Geiger

2) Checkerboard artifacts introduced by upsampling cannot explain the spectral discrepancies alone as the generator is able to compensate for these artifacts.

GRAF: Generative Radiance Fields for 3D-Aware Image Synthesis

1 code implementation NeurIPS 2020 Katja Schwarz, Yiyi Liao, Michael Niemeyer, Andreas Geiger

In contrast to voxel-based representations, radiance fields are not confined to a coarse discretization of the 3D space, yet allow for disentangling camera and scene properties while degrading gracefully in the presence of reconstruction ambiguity.

Towards Unsupervised Learning of Generative Models for 3D Controllable Image Synthesis

1 code implementation CVPR 2020 Yiyi Liao, Katja Schwarz, Lars Mescheder, Andreas Geiger

We define the new task of 3D controllable image synthesis and propose an approach for solving it by reasoning both in 3D space and in the 2D image domain.
