Peter Hedman

I’m a researcher at Google DeepMind in London, where I’m building immersive 3D experiences.

I’ve worked on 3D photos (1, 2, 3), 3D videos, and NeRF flythroughs for Google Maps. Formally my research interests are view synthesis, image-based rendering, neural rendering and real-time graphics.
