Texture-Consistent 3D Scene Style Transfer via Transformer-Guided Neural Radiance Fields

Abstract

Recent advancements have suggested that neural radiance fields (NeRFs) show great potential in 3D style transfer. However, most existing NeRF-based style transfer methods still face considerable challenges in generating stylized images that simultaneously preserve clear scene textures and maintain strong cross-view consistency. To address these limitations, in this paper, we propose a novel transformer-guided approach for 3D scene style transfer. Specifically, we first design a transformer-based style transfer network to capture long-range dependencies and generate 2D stylized images with initial consistency, which serve as supervision for the 3D stylized generation. To enable fine-grained control over style, we propose a latent style vector as a conditional feature and design a style network that projects this style information into the 3D space. We further develop a merge network that integrates style features with scene geometry to render 3D stylized images that are both visually coherent and stylistically consistent. In addition, we propose a texture consistency loss to preserve scene structure and enhance texture fidelity across views. Extensive quantitative and qualitative experimental results demonstrate that our proposed approach outperforms many state-of-the-art methods in terms of visual perception, image quality and multi-view consistency.
