AI总结:

针对现有妆容迁移方法存在身份偏移、无实时能力及时序一致性差的问题,提出将妆容迁移解耦为透明掩膜提取与图形学渲染两步的框架,搭配专用训练目标,在细节保留、时序稳定和身份保留上优于现有基准,可实现实时试妆。

摘要:

我们提出了一种用于实时虚拟试妆的新型框架,可实现高保真、保留身份特征的妆容迁移,同时具备稳健的时序一致性。在实时妆容迁移应用中,合成时序连贯的结果、精准复刻精细妆容并保留用户身份特征至关重要。然而,现有方法通常难以将半透明妆容与肤色及其他身份特征解耦,导致身份偏移并引发公平性问题。此外,当前方法不具备实时能力,也无法维持时序一致性,限制了实际应用。为解决这些挑战,我们将妆容迁移解耦为两个步骤:透明妆容掩膜提取与基于图形学的掩膜渲染。在妆容提取步骤后,妆容渲染可实时完成,从而支持实时试妆。我们的妆容提取模型基于伪真值数据训练,这些数据通过两种互补方法生成:基于图形学的渲染管线与无监督k-means聚类方法。为进一步提升透明度估计与色彩保真度,我们提出了专门的训练目标,包括alpha加权重建损失与唇色损失。我们的方法可在不同姿态、表情与肤色下实现稳健的妆容迁移,同时保持时序平滑性。大量实验表明,我们的方法在捕捉精细细节、维持时序稳定性与保留身份完整性方面优于现有基准方法。

英文摘要:

We present a novel framework for real-time virtual makeup try-on that achieves high-fidelity, identity-preserving cosmetic transfer with robust temporal consistency. In live makeup transfer applications, it is critical to synthesize temporally coherent results that accurately replicate fine-grained makeup and preserve user's identity. However, existing methods often struggle to disentangle semitransparent cosmetics from skin tones and other identify features, causing identity shifts and raising fairness concerns. Furthermore, current methods lack real-time capabilities and fail to maintain temporal consistency, limiting practical adoption. To address these challenges, we decouple makeup transfer into two steps: transparent makeup mask extraction and graphics-based mask rendering. After the makeup extraction step, the makeup rendering can be performed in real time, enabling live makeup try-on. Our makeup extraction model trained on pseudo-ground-truth data generated via two complementary methods: a graphics-based rendering pipeline and an unsupervised k-means clustering approach. To further enhance transparency estimation and color fidelity, we propose specialized training objectives, including alpha-weighted reconstruction and lip color losses. Our method achieves robust makeup transfer across diverse poses, expressions, and skin tones while preserving temporal smoothness. Extensive experiments demonstrate that our approach outperforms existing baselines in capturing fine details, maintaining temporal stability, and preserving identity integrity.
