📝 摘要(中文)
基于扩散的生成AI在电子商务应用中取得了显著成功,如虚拟试穿和产品背景合成。然而,消费者在购买服装时希望能够详细查看特定区域,如领口和面料纹理,但现有方法未能明确研究这一需求。为此,本文正式提出了一项新的非模板任务:时尚细节生成,并发布了FDBench,这是第一个包含40K+人类验证的参考细节对的基准。为了解决模型在生成细节时的语义差距,本文提出了跨模态特征对齐蒸馏(CFAD),并引入了一种一致性奖励模型以优化生成效果。实验表明,DetailAnywhere在所有指标和人类评估中显著优于现有开源方法。
🔬 方法详解
问题定义:本文旨在解决时尚细节生成中的语义差距问题,现有方法无法有效生成与参考图像对应的细节区域,且缺乏精确提示。
核心思路:通过引入跨模态特征对齐蒸馏(CFAD),利用经过微调的DINOv3教师模型对多模态扩散变换器的两个分支进行对齐,从而在共享的语义空间中生成高质量的细节图像。
技术框架:整体架构包括两个主要模块:一是多模态扩散变换器,二是一致性奖励模型。前者负责生成细节图像,后者则通过对图像对的质量进行评分来优化生成过程。
关键创新:最重要的技术创新在于引入了一致性奖励模型,通过联合评分图像对的质量,提升生成细节与参考图像的一致性,这在现有方法中尚未实现。
关键设计:在模型设计中,采用了双分支结构,损失函数结合了生成质量和一致性评分,确保生成的细节既真实又符合参考图像的特征。

🎯 应用场景
该研究的潜在应用领域包括电子商务平台的服装展示、虚拟试穿系统以及在线购物体验的提升。通过提供高质量的细节生成,消费者能够更好地理解产品特性,从而做出更明智的购买决策,未来可能对时尚行业的在线销售模式产生深远影响。
📄 摘要(原文)
Diffusion-based generative AI has achieved remarkable success in e-commerce applications such as virtual try-on, poster generation, and product background synthesis. However, when making online purchasing decisions for apparel, consumers also desire the freedom to examine specific detail regions of interest, such as collars, cuffs, and fabric textures, yet existing methods have not explicitly studied this setting. We therefore formalize a new, non-template task: Fashion Detail Generation with focus conditioning, and release FDBench, the first benchmark comprising 40K+ human-verified reference-detail pairs across 41 different categories. This task poses a unique semantic gap challenge: the model must bridge the correspondence between a focus marker on a product reference image and a photorealistic close-up view of the indicated region, while faithfully preserving the garment's identity, without any precise prompt. To bridge this gap, we propose Cross-modal Feature Alignment Distillation (CFAD), which leverages a fine-tuned DINOv3 teacher to align both branches of a Multimodal Diffusion Transformer in a shared semantic space via dual-branch distillation. To further improve consistency between generated details and reference images, we introduce a consistency reward model that jointly scores image pairs along three quality axes and optimizes generation via reinforcement learning. Experiments show that our model DetailAnywhere significantly outperforms all state-of-the-art opensource methods across all metrics and human evaluations.
