• Abstract: We present FPRF, a feed-forward photorealistic style transfer method for large-scale 3D neural radiance fields. FPRF stylizes large-scale 3D scenes with arbitrary, multiple style reference images without additional optimization while preserving multi-view appearance consistency. Prior arts required tedious per-style/-scene optimization and were limited to small-scale 3D scenes. FPRF efficiently stylizes large-scale 3D scenes by introducing a style-decomposed 3D neural radiance field, which inherits AdaIN's feed-forward stylization machinery, supporting arbitrary style reference images. Furthermore, FPRF supports multi-reference stylization with the semantic correspondence matching and local AdaIN, which adds diverse user control for 3D scene styles. FPRF also preserves multi-view consistency by applying semantic matching and style transfer processes directly onto queried features in 3D space. In experiments, we demonstrate that FPRF achieves favorable photorealistic quality 3D scene stylization for large-scale scenes with diverse reference images.

• G3DST: Generalizing 3D Style Transfer with Neural Radiance Fields across Scenes and Styles [45.92812062685523]
  Existing methods for 3D style transfer need extensive per-scene optimization for single or multiple styles. In this work, we overcome the limitations of existing methods by rendering stylized novel views from a NeRF without the need for per-scene or per-style optimization. Our findings demonstrate that this approach achieves a good visual quality comparable to that of per-scene methods.

  We propose a simple yet effective pipeline for stylizing a 3D scene.

  3D sceneization extends the work of neural style transfer to 3D. A vital challenge in this problem is to maintain the uniformity of the stylized appearance across multiple views. We propose a novel architecture trained on a collection of style images that, at test time, produces real time high-quality stylized novel views.

  We propose to use a neural radiance field (NeRF) to represent 3D human face and combine it with 2D style transfer to stylize the 3D face. We find that directly training a NeRF on stylized images from 2D style transfer brings in 3D inconsistency issue and causes blurriness. We propose a hybrid framework of NeRF and meshization to combine the benefits of high fidelity geometry reconstruction of NeRF and fast speed rendering of mesh.

  StyleRF (Style Radiance Fields) is an innovative 3D style transfer technique. It employs an explicit grid of high-level features to represent 3D scenes, with which high-fidelity geometry can be reliably restored via volume rendering. It transforms the grid features according to the reference style which directly leads to high-quality zero-shot style transfer.
