arXiv:2312.02218v3 Announce Type: replace
Abstract: Dynamic Neural Radiance Fields (Dynamic NeRF) enhance NeRF technology to model moving scenes. However, they are resource intensive and challenging to compress. To address these issues, this paper presents WavePlanes, a fast and more compact explicit model. We propose a multi-scale space and space-time feature plane representation using N-level 2-D wavelet coefficients. The inverse discrete wavelet transform reconstructs feature signals at varying detail, which are linearly decoded to approximate the color and density of volumes …
