NeRF in the Wild: Neural Radiance Fields for Unconstrained Photo Collections [PDF]

2021 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), 2021
We present a learning-based method for synthesizing novel views of complex scenes using only unstructured collections of in-the-wild photographs. We build on Neural Radiance Fields (NeRF), which uses the weights of a multilayer perceptron to model the density and color of a scene as a function of 3D coordinates.

NeRF-QA: Neural Radiance Fields Quality Assessment Database

2023 15th International Conference on Quality of Multimedia Experience (QoMEX), 2023
This short paper proposes a new database - NeRF-QA - containing 48 videos synthesized with seven NeRF based methods, along with their perceived quality scores, resulting from subjective assessment tests; for the videos selection, both real and synthetic, 360 degrees scenes were considered.

NeRF applied to satellite imagery for surface reconstruction

, 2023
We present Surf-NeRF, a modified implementation of the recently introduced Shadow Neural Radiance Field (S-NeRF) model. This method is able to synthesize novel views from a sparse set of satellite images of a scene, while accounting for the variation in ...

Efficient View Synthesis with Neural Radiance Distribution Field

, 2023
Recent work on Neural Radiance Fields (NeRF) has demonstrated significant advances in high-quality view synthesis. A major limitation of NeRF is its low rendering efficiency due to the need for multiple network forwardings to render a single pixel ...

NeRF-Loc: Visual Localization with Conditional Neural Radiance Field

2023 IEEE International Conference on Robotics and Automation (ICRA), 2023
We propose a novel visual re-localization method based on direct matching between the implicit 3D descriptors and the 2D image with transformer. A conditional neural radiance field(NeRF) is chosen as the 3D scene representation in our pipeline, which supports continuous 3D descriptors generation and neural rendering.
