Omni-NeRF: Neural Radiance Field from 360° Image Captures

WebNeural radiance fields (NeRF) have shown great potentials in representing 3D scenes and synthesizing novel views, but the computational overhead of NeRF at the inference stage is still heavy. To alleviate the burden, we delve into the coarse-to-fine, hierarchical sampling procedure of NeRF and point out that the coarse stage can be replaced by a lightweight … Web29 de ago. de 2024 · Hierarchical Volume Sampling.

Web24 de out. de 2024 · To improve computational efficiency, we made several modifications to the original NeRF model. 1) Instead of using two-stage MLPs with hierarchical sampling, we only use a single MLP with stratified sampling; 2) The network width is reduced from 256 to 128; 3) Each ray is discretized uniformly into 128 points. WebRow 1 shows a minimalist version of our model without positional encoding (PE), view-dependence (VD), or hierarchical sampling (H). In rows 2–4 we remove these three components one at a time from the full model, observing that positional encoding provides the largest quantitative benefit of these three contributions (row 2), followed by view …
