Peter Hedman

Hi! I'm Peter Hedman, a researcher at Google DeepMind in London.

My focus is on creating immersive 3D experiences from easy-to-capture footage of real places. For example, you may want to scan and digitally revisit your childhood home, or capture a VR-ready 3D panorama of the places you visit during a vacation.

Formally my research interests are view synthesis, image-based rendering, neural rendering and real-time graphics.
