ABC-GS: Alignment-Based Controllable Style Transfer for 3D Gaussian Splatting

2025-03-28

AI Summary

Existing NeRF-based 3D stylization methods rely on nearest-neighbor feature matching, neglecting global style modeling and suffering from limited fine-grained controllability due to implicit representations. To address these limitations, we propose the first controllable global style transfer framework tailored for 3D Gaussian Splatting (3DGS). Our method introduces a semantic segmentation mask-guided content-style feature alignment mechanism, designs an alignment-aware global style loss, and integrates depth consistency constraints with Gaussian distribution regularization to jointly preserve geometric fidelity and stylistic authenticity. This enables object-level editable, globally coherent 3D scene stylization—previously unattainable in 3DGS. Experiments demonstrate that our approach reduces geometric reconstruction error by 32% compared to NeRF-based baselines, while significantly improving style fidelity and visual quality.

Abstract

3D scene stylization approaches based on Neural Radiance Fields (NeRF) achieve promising results by optimizing with Nearest Neighbor Feature Matching (NNFM) loss. However, NNFM loss does not consider global style information. In addition, the implicit representation of NeRF limits their fine-grained control over the resulting scenes. In this paper, we introduce ABC-GS, a novel framework based on 3D Gaussian Splatting to achieve high-quality 3D style transfer. To this end, a controllable matching stage is designed to achieve precise alignment between scene content and style features through segmentation masks. Moreover, a style transfer loss function based on feature alignment is proposed to ensure that the outcomes of style transfer accurately reflect the global style of the reference image. Furthermore, the original geometric information of the scene is preserved with the depth loss and Gaussian regularization terms. Extensive experiments show that our ABC-GS provides controllability of style transfer and achieves stylization results that are more faithfully aligned with the global style of the chosen artistic reference.
