Transcript
Dear Fellow Scholars, this is Two Minute Papers with Dr. Károly Zsolnai-Fehér. Approximately 5 months ago, we talked about a technique called Neural Radiance Fields, or NERF in short, that worked on a 5D neural radiance field representation. So what does this mean exactly? What this means is that we have 3 dimensions for location and two for view d... Read More
Questions & Answers
Q: What is NERF?
NERF is a technique that uses neural networks to learn and synthesize new views of scenes based on a 5D neural radiance field representation.
Q: What were the limitations of NERF?
NERF had trouble with scenes that had variable lighting conditions and lots of occluders, which affected its ability to accurately reconstruct scenes.
Q: How does NERF-W improve upon NERF?
NERF-W is a new technique developed by scientists at Google Research that can handle scenes with variable lighting conditions and occluders, resulting in more consistent and improved reconstruction results.
Q: How does NERF-W understand lighting and geometry?
NERF-W can disentangle lighting and geometry in scenes, allowing it to change both viewpoint and lighting conditions while reconstructing the scene accurately.
