ASSR-NeRF: Arbitrary-Scale Super-Resolution on Voxel Grid for
High-Quality Radiance Fields Reconstruction
NeRF-based methods reconstruct 3D scenes by building a radiance field with implicit or explicit representations. While NeRF-based methods can perform novel view synthesis (NVS) at arbitrary scale, the performance in high-resolution novel view synthesis (HRNVS) with low-resolution (LR) optimization often results in oversmoothing. On the other hand, single-image super-resolution (SR) …
