Fast radiance field reconstruction from sparse inputs

Song Lai, Linyan Cui, Jihao Yin

Abstract: Highlights•A fast radiance field reconstruction method from a sparse set of images with silhouettes.•An explicit–implicit radiance field representation integrating NeRF and Shape from Silhouette.•Voxel dilating and pruning schemes refining the geometry prediction.•A total variation loss encouraging smooth radiance field reconstruction.
