Instant Continual Learning of Neural Radiance Fields

no code implementations4 Sep 2023 Ryan Po, Zhengyang Dong, Alexander W. Bergman, Gordon Wetzstein

Neural radiance fields (NeRFs) have emerged as an effective method for novel-view synthesis and 3D scene reconstruction.

Efficient 3D Articulated Human Generation with Layered Surface Volumes

no code implementations11 Jul 2023 Yinghao Xu, Wang Yifan, Alexander W. Bergman, Menglei Chai, Bolei Zhou, Gordon Wetzstein

These layers are rendered using alpha compositing with fast differentiable rasterization, and they can be interpreted as a volumetric representation that allocates its capacity to a manifold of finite thickness around the template.

Articulated 3D Head Avatar Generation using Text-to-Image Diffusion Models

no code implementations10 Jul 2023 Alexander W. Bergman, Wang Yifan, Gordon Wetzstein

Recent work on text-guided 3D object generation has shown great promise in addressing these needs.

Generative Neural Articulated Radiance Fields

no code implementations28 Jun 2022 Alexander W. Bergman, Petr Kellnhofer, Wang Yifan, Eric R. Chan, David B. Lindell, Gordon Wetzstein

Unsupervised learning of 3D-aware generative adversarial networks (GANs) using only collections of single-view 2D photographs has very recently made much progress.

Fast Training of Neural Lumigraph Representations using Meta Learning

no code implementations NeurIPS 2021 Alexander W. Bergman, Petr Kellnhofer, Gordon Wetzstein

Inspired by neural variants of image-based rendering, we develop a new neural rendering approach with the goal of quickly learning a high-quality representation which can also be rendered in real-time.

ScanGAN360: A Generative Model of Realistic Scanpaths for 360$^{\circ}$ Images

no code implementations25 Mar 2021 Daniel Martin, Ana Serrano, Alexander W. Bergman, Gordon Wetzstein, Belen Masia

Generative adversarial approaches could alleviate this challenge by generating a large number of possible scanpaths for unseen images.

Implicit Neural Representations with Periodic Activation Functions

24 code implementations NeurIPS 2020 Vincent Sitzmann, Julien N. P. Martel, Alexander W. Bergman, David B. Lindell, Gordon Wetzstein

However, current network architectures for such implicit neural representations are incapable of modeling signals with fine detail, and fail to represent a signal's spatial and temporal derivatives, despite the fact that these are essential to many physical signals defined implicitly as the solution to partial differential equations.
