📝 摘要(中文)
3D高斯点云(3DGS)最近在新视图合成和3D重建领域取得了重大进展,但在场景内容外观编辑方面仍存在效率低和缺乏真实感的问题。本文提出VIRGi,一种快速编辑3DGS场景颜色的方法,同时保留视角依赖效果,如高光。该方法的关键在于一种新颖的架构,将颜色分为漫反射和视角依赖成分,并采用多视角训练策略,整合来自多个视点的图像补丁。通过微调单个多层感知机的权重,结合单次分割模块,用户仅需手动编辑一张图像,便可在两秒内将颜色编辑无缝传播至整个场景,支持实时交互并控制视角依赖效果的强度。对多种数据集的全面验证显示,VIRGi在定量和定性上显著优于基于神经辐射场的竞争方法。
🔬 方法详解
问题定义:本文旨在解决3D高斯点云(3DGS)场景颜色编辑的效率和真实感不足的问题。现有方法在处理视角依赖效果时表现不佳,无法满足用户对快速编辑的需求。
核心思路:VIRGi的核心思路是将颜色分为漫反射和视角依赖成分,通过多视角训练策略来提高编辑效果的真实性和准确性。该设计使得在编辑时能够保留重要的视角依赖特征。
技术框架:VIRGi的整体架构包括两个主要模块:一是颜色分离网络,负责将颜色信息分为漫反射和视角依赖成分;二是多视角训练模块,整合来自不同视点的图像补丁,以增强模型的泛化能力。
关键创新:VIRGi的关键创新在于其快速的颜色编辑方案,仅需用户手动编辑一张图像,便可通过微调单个多层感知机的权重,实现对整个场景的颜色传播。这一方法在效率和效果上均优于传统的单视图训练方法。
关键设计:在设计中,VIRGi采用了特定的损失函数以优化漫反射和视角依赖成分的重建质量,同时在网络结构上引入了单次分割模块,以便快速识别可编辑区域。

📄 摘要(原文)
3D Gaussian Splatting (3DGS) has recently transformed the fields of novel view synthesis and 3D reconstruction due to its ability to accurately model complex 3D scenes and its unprecedented rendering performance. However, a significant challenge persists: the absence of an efficient and photorealistic method for editing the appearance of the scene's content. In this paper we introduce VIRGi, a novel approach for rapidly editing the color of scenes modeled by 3DGS while preserving view-dependent effects such as specular highlights. Key to our method are a novel architecture that separates color into diffuse and view-dependent components, and a multi-view training strategy that integrates image patches from multiple viewpoints. Improving over the conventional single-view batch training, our 3DGS representation provides more accurate reconstruction and serves as a solid representation for the recoloring task. For 3DGS recoloring, we then introduce a rapid scheme requiring only one manually edited image of the scene from the end-user. By fine-tuning the weights of a single MLP, alongside a module for single-shot segmentation of the editable area, the color edits are seamlessly propagated to the entire scene in just two seconds, facilitating real-time interaction and providing control over the strength of the view-dependent effects. An exhaustive validation on diverse datasets demonstrates significant quantitative and qualitative advancements over competitors based on Neural Radiance Fields representations.
