📝 摘要(中文)

尽管视频虚拟试穿(VVT)在动态主体上合成逼真的服装覆盖方面取得了显著进展,但现有方法仍然受到源相机轨迹的被动依赖,无法满足全方位视角探索的互动自由。为了解决这一限制,本文定义了一个开创性的研究前沿:相机可控视频虚拟试穿(CaM-VVT)。与传统VVT不同,CaM-VVT不仅需要视角无关的纹理幻觉,还要求在任意相机运动下非刚性人体动态与背景上下文之间的严格结构同步。为应对这些挑战,本文提出了TryOnCrafter,这是第一个专门为CaM-VVT任务设计的统一DiT框架。

🔬 方法详解

问题定义:本文旨在解决现有视频虚拟试穿方法在相机轨迹上的被动依赖,导致的视角探索受限问题。现有方法无法实现动态场景中的非刚性人体与背景的同步。

核心思路:提出相机可控视频虚拟试穿(CaM-VVT)概念,通过引入可渲染的4D试穿代理,显式解耦人类主体与环境,从而实现更高的互动性和真实感。

技术框架:TryOnCrafter框架包括多个模块:首先,利用高保真2D试穿先验生成3D服装模型;其次,通过SMPL-X序列对模型进行动画处理;最后,将其与重建的背景点云进行对齐,确保合成视频的结构一致性。

关键创新:最重要的创新在于引入了可渲染的4D试穿代理,提供了一个强大的结构基础,确保合成视频在物理上合理且符合预设轨迹,与现有方法相比,显著提高了纹理密度和运动完整性。

关键设计:在设计中,采用了基于DiT的生成模型,结合了特定的损失函数以优化纹理和结构的同步性,同时在网络结构上进行了针对性的调整,以适应4D代理的编辑性。

📄 摘要(原文)

While Video Virtual Try-on (VVT) has achieved remarkable progress in synthesizing realistic garment overlays on dynamic subjects, existing paradigms remains fundamentally constrained by a passive dependency on source camera trajectories, failing to accommodate the requisite interactive freedom for omnidirectional viewpoint exploration. To address this limitation, we define a pioneering research frontier: Camera-controllable Video Virtual Try-on (CaM-VVT). Unlike conventional VVT, CaM-VVT not only necessitates viewpoint-agnostic texture hallucination but also strict structural synchronization between non-rigid human dynamics and background contexts under arbitrary, unconstrained camera movements. To tackle these challenges, we present TryOnCrafter, the first unified DiT-based framework specifically architected for the CaM-VVT task. Departing from implicit pixel-space manipulation, we introduce a Renderable 4D Try-on Proxy that explicitly decouples the human subject from the environment. This is achieved by distilling high-fidelity 2D try-on priors into a clothed 3DGS-based avatar, which is subsequently animated via SMPL-X sequences and metric-aligned into a reconstructed background point cloud. This proxy establishes a robust structural foundation with superior texture density and motion integrity. Our Proxy-Anchored Video DiT leverages this robust structural foundation as a primary geometric anchor, ensuring that the synthesized photorealistic videos are strictly constrained by prescribed trajectories and physically plausible deformations. Benefiting from the inherent editability of the 4D proxy, TryOnCrafter facilitates diverse downstream applications, including human relocalization, ``bullet time'' effects, and $360$-degree orbital viewing.
