3D Dataset Distillation: Condensing 3D Datasets for Enhanced Data Efficiency in 3D Reconstruction.
NeRD is a principled system for distilling 3D datasets while keeping the NeRF model fixed: it iteratively prunes redundant views using projection-validity and depth-consistency constraints to preserve independent spatial information. Across benchmarks, near-full reconstruction quality holds with as little as 40% of the original data — suggesting viewpoint diversity matters more than dataset size. Conducted at Georgia Tech's Efficient and Intelligent Computing Lab.
