NeRFiller: Completing Scenes via Generative 3D Inpainting

no code implementations7 Dec 2023 Ethan Weber, Aleksander Hołyński, Varun Jampani, Saurabh Saxena, Noah Snavely, Abhishek Kar, Angjoo Kanazawa

In contrast to related works, we focus on completing scenes rather than deleting foreground objects, and our approach does not require tight 2D object masks or text.

Nerfbusters: Removing Ghostly Artifacts from Casually Captured NeRFs

1 code implementation ICCV 2023 Frederik Warburg, Ethan Weber, Matthew Tancik, Aleksander Holynski, Angjoo Kanazawa

Casually captured Neural Radiance Fields (NeRFs) suffer from artifacts such as floaters or flawed geometry when rendered outside the camera trajectory.

2 code implementations8 Feb 2023 Matthew Tancik, Ethan Weber, Evonne Ng, RuiLong Li, Brent Yi, Justin Kerr, Terrance Wang, Alexander Kristoffersen, Jake Austin, Kamyar Salahi, Abhik Ahuja, David McAllister, Angjoo Kanazawa

Neural Radiance Fields (NeRF) are a rapidly growing area of research with wide-ranging applications in computer vision, graphics, robotics, and more.

Studying Bias in GANs through the Lens of Race

no code implementations6 Sep 2022 Vongani H. Maluleke, Neerja Thakkar, Tim Brooks, Ethan Weber, Trevor Darrell, Alexei A. Efros, Angjoo Kanazawa, Devin Guillory

In this work, we study how the performance and evaluation of generative image models are impacted by the racial composition of their training datasets.

The One Where They Reconstructed 3D Humans and Environments in TV Shows

no code implementations28 Jul 2022 Georgios Pavlakos, Ethan Weber, Matthew Tancik, Angjoo Kanazawa

TV shows depict a wide variety of human behaviors and have been studied extensively for their potential to be a rich source of data for many applications.

Scaling up instance annotation via label propagation

no code implementations ICCV 2021 Dim P. Papadopoulos, Ethan Weber, Antonio Torralba

Through a large-scale experiment to populate 1M unlabeled images with object segmentation masks for 80 object classes, we show that (1) we obtain 1M object segmentation masks with an total annotation time of only 290 hours; (2) we reduce annotation time by 76x compared to manual annotation; (3) the segmentation quality of our masks is on par with those from manually annotated datasets.
