Phys.org  November 19, 2024 An international team of researchers (Canada, USA – Stanford University) presented an imaging and neural rendering technique that seeks to synthesize videos of light propagating through a scene from novel, moving camera viewpoints. They used a new ultrafast imaging setup to capture a first-of-its kind, multi-viewpoint video dataset with picosecond-level temporal resolution. Combined with this dataset, they introduced an efficient neural volume rendering framework based on the transient field defined as a mapping from a 3D point and 2D direction to a high-dimensional, discrete-time signal that represented time-varying radiance at ultrafast timescales. They rendered a range […]
