HyperNeRF: A Higher-Dimensional Representation for Topologically Varying Neural Radiance Fields

1 code implementation24 Jun 2021 Keunhong Park, Utkarsh Sinha, Peter Hedman, Jonathan T. Barron, Sofien Bouaziz, Dan B Goldman, Ricardo Martin-Brualla, Steven M. Seitz

A common approach to reconstruct such non-rigid scenes is through the use of a learned deformation field mapping from coordinates in each input image into a canonical template coordinate space.

FiG-NeRF: Figure-Ground Neural Radiance Fields for 3D Object Category Modelling

no code implementations17 Apr 2021 Christopher Xie, Keunhong Park, Ricardo Martin-Brualla, Matthew Brown

We investigate the use of Neural Radiance Fields (NeRF) to learn high quality 3D object category models from collections of input images.

Nerfies: Deformable Neural Radiance Fields

1 code implementation25 Nov 2020 Keunhong Park, Utkarsh Sinha, Jonathan T. Barron, Sofien Bouaziz, Dan B Goldman, Steven M. Seitz, Ricardo Martin-Brualla

We present the first method capable of photorealistically reconstructing deformable scenes using photos/videos captured casually from mobile phones.
