PointNeRF++: A multi-scale, point-based Neural Radiance Field

arXiv:2312.02362v2 Announce Type: replace
Abstract: Point clouds offer an attractive source of information to complement images in neural scene representations, especially when few images are available. Neural rendering methods based on point clouds do exist, but they do not perform well when the point cloud quality is low -- e.g., sparse or incomplete, which is often the case with real-world data. We overcome these problems with a simple representation that aggregates point clouds at multiple scale levels with sparse voxel …
