Space-time Neural Irradiance Fields for Free-Viewpoint Video

Understand

We present a method that learns a spatiotemporal neural irradiance field for dynamic scenes from a single video.

• Our learned representation enables free-viewpoint rendering of the input video.
• Our method builds upon recent advances in implicit representations.
• Learning a spatiotemporal irradiance field from a single video poses significant challenges because the video contains only one observation of the scene at any point in time.
