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.

Nerfies: Deformable Neural Radiance Fields

1 code implementation ICCV 2021 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.

Real-time Burst Photo Selection Using a Light-Head Adversarial Network

no code implementations20 Mar 2018 Baoyuan Wang, Noranart Vesdapunt, Utkarsh Sinha, Lei Zhang

The system is designed to run in the viewfinder mode and capture a burst sequence of frames before and after the shutter is pressed.

Comparison of Optimization Methods in Optical Flow Estimation

no code implementations2 May 2016 Noranart Vesdapunt, Utkarsh Sinha

In this paper, we assumed slightly uniform change of velocity between two nearby frames, and solve the optical flow problem by traditional method, Lucas-Kanade(1981).
