WebWe present Block-NeRF, a variant of Neural Radiance Fields that can represent large-scale environments. Specifically, we demonstrate that when scaling NeRF to render city-scale scenes spanning multiple blocks, it is vital to decompose … WebGitHub Gist: instantly share code, notes, and snippets.

Web12 aug. 2024 · We leverage the expression space of a 3D morphable face model (3DMM) to represent the distribution of human facial expressions, and use it to condition the NeRF volumetric function. Furthermore, we impose a spatial prior brought by 3DMM fitting to guide the network to learn disentangled control for scene appearance and facial actions. Web16 mrt. 2024 · We introduce the Satellite Neural Radiance Field (Sat-NeRF), a new end-to-end model for learning multi-view satellite photogrammetry in the wild. Sat-NeRF combines some of the latest trends in neural rendering with native satellite camera models, represented by rational polynomial coefficient (RPC) functions. The proposed method … WebMega-NeRF (ours) further decomposes the foreground into a set of spatial cells, learning a separate NeRF for each. Each cell-specific submodule can be trained independently and … ukri healthy ageing challenge
