摘要:

虚拟试穿是一个具有很高商业价值的计算机视觉课题,其目标是在人物图像上以照片级真实效果展示新服装的穿着效果。以往研究在单一阶段完成形状与内容推理,采用单尺度形变机制和相对简单的内容推理机制,导致在具有挑战性的试穿场景下服装形变和皮肤保留效果欠佳。为解决这些局限,我们提出了一种基于渐进推理范式的新型虚拟试穿方法(PG-VTON),该方法利用自顶向下的推理流程和通用服装试穿策略。具体而言,我们通过解耦语义类别并引入一致性,提出了一种鲁棒的试穿解析推理方法。以试穿解析结果作为形状引导,我们通过形变-映射-合成实现服装试穿。为适应广泛的试穿场景,我们采用“覆盖更多并选择一个”的形变策略,并基于对齐情况显式区分任务。此外,我们调节StyleGAN2,以目标皮肤形状和空间无关的皮肤特征为条件,实现重新裸露皮肤的修复。实验表明,我们的方法在两种具有挑战性的场景下达到了最先进的性能。代码将公开于https://github.com/NerdFNY/PGVTON。

英文摘要:

Virtual try-on is a promising computer vision topic with a high commercial value wherein a new garment is visually worn on a person with a photo-realistic effect. Previous studies conduct their shape and content inference at one stage, employing a single-scale warping mechanism and a relatively unsophisticated content inference mechanism. These approaches have led to suboptimal results in terms of garment warping and skin reservation under challenging try-on scenarios. To address these limitations, we propose a novel virtual try-on method via progressive inference paradigm (PGVTON) that leverages a top-down inference pipeline and a general garment try-on strategy. Specifically, we propose a robust try-on parsing inference method by disentangling semantic categories and introducing consistency. Exploiting the try-on parsing as the shape guidance, we implement the garment try-on via warping-mapping-composition. To facilitate adaptation to a wide range of try-on scenarios, we adopt a covering more and selecting one warping strategy and explicitly distinguish tasks based on alignment. Additionally, we regulate StyleGAN2 to implement re-naked skin inpainting, conditioned on the target skin shape and spatial-agnostic skin features. Experiments demonstrate that our method has state-of-the-art performance under two challenging scenarios. The code will be available at https://github.com/NerdFNY/PGVTON.
