CVPR 2026

We consider the problem of imaging a dynamic scene when scene appearance variations can outpace photon arrivals. Under such conditions, a pixel is effectively "blind" to changes in appearance that occur within the timespan separating the photons it detects, and so the inter-photon interval presents

Neural Inverse Rendering from Propagating Light

Anagh Malik, Benjamin Attal, Andrew Xie, Matthew O'Toole, David B. Lindell

CVPR 2025poster

We present the first system for physically based, neural inverse rendering from multi-viewpoint videos of propagating light. Our approach relies on a time-resolved extension of neural radiance caching -- a technique that accelerates inverse rendering by storing infinite-bounce radiance arriving at a…
