摘要:

尽管基于扩散的图像虚拟试衣取得了相当大的进展,但新兴方法仍然难以有效解决手部遮挡(即服装区域被手部遮挡)问题,导致试衣性能显著下降。为了解决现实场景中广泛存在的这一问题,我们提出了 VTON-HandFit,利用手部先验的力量来重建手部遮挡情况下的外观和结构。首先,我们定制了一个 Handpose Aggregation Net,使用基于 ControlNet 的结构显式且自适应地编码全局手部和姿态先验。此外,为了充分利用手部相关结构和外观信息,我们提出了 Hand-feature Disentanglement Embedding 模块,将手部先验解耦为手部结构参数特征和视觉外观特征,并定制了掩码交叉注意力用于进一步解耦特征嵌入。最后,我们定制了手部边缘约束损失,以更好地从模型图像的手部模板中学习结构边缘知识。VTON-HandFit 在公开数据集和我们自收集的手部遮挡 Handfit-3K 数据集上的定性和定量评估中均优于基线方法,特别适用于现实场景中的任意手部姿态遮挡情况。代码和数据集将在 https://github.com/VTON-HandFit/VTON-HandFit 上提供。

英文摘要:

Although diffusion-based image virtual try-on has made considerable progress, emerging approaches still struggle to effectively address the issue of hand occlusion (i.e., clothing regions occluded by the hand part), leading to a notable degradation of the try-on performance. To tackle this issue widely existing in real-world scenarios, we propose VTON-HandFit, leveraging the power of hand priors to reconstruct the appearance and structure for hand occlusion cases. Firstly, we tailor a Handpose Aggregation Net using the ControlNet-based structure explicitly and adaptively encoding the global hand and pose priors. Besides, to fully exploit the hand-related structure and appearance information, we propose Hand-feature Disentanglement Embedding module to disentangle the hand priors into the hand structure-parametric and visual-appearance features, and customize a masked cross attention for further decoupled feature embedding. Lastly, we customize a hand-canny constraint loss to better learn the structure edge knowledge from the hand template of model image. VTON-HandFit outperforms the baselines in qualitative and quantitative evaluations on the public dataset and our self-collected hand-occlusion Handfit-3K dataset particularly for the arbitrary hand pose occlusion cases in real-world scenarios. The Code and dataset will be available at \url{https://github.com/VTON-HandFit/VTON-HandFit}.
