摘要:

近期文本到图像扩散模型的进步显著提升了图像定制质量,能够合成高度逼真的图像。尽管取得进展,实现快速高效个性化仍是关键挑战,尤其在现实应用中。现有方法主要通过注入身份特定嵌入加速人类主体定制,但这些策略难以推广到任意对象类别,限制了其适用性。为解决此问题,我们提出一种新框架,利用学习网络预测对象特定的文本逆向嵌入,并将其整合到扩散模型的UNet时间步中,用于文本条件定制。此设计使在单次前向传递中能够快速实现广泛对象的零样本个性化,兼具灵活性和可扩展性。在多个任务和设置中的广泛实验验证了方法的有效性,突显其在支持快速、多样和包容性图像定制方面的潜力。据我们所知,这项工作是首次在扩散模型中实现此类通用、无需训练的个性化尝试,为未来个性化图像生成研究铺平道路。

英文摘要:

Recent advances in text-to-image diffusion models have substantially improved the quality of image customization, enabling the synthesis of highly realistic images. Despite this progress, achieving fast and efficient personalization remains a key challenge, particularly for real-world applications. Existing approaches primarily accelerate customization for human subjects by injecting identity-specific embeddings into diffusion models, but these strategies do not generalize well to arbitrary object categories, limiting their applicability. To address this limitation, we propose a novel framework that employs a learned network to predict object-specific textual inversion embeddings, which are subsequently integrated into the UNet timesteps of a diffusion model for text-conditional customization. This design enables rapid, zero-shot personalization of a wide range of objects in a single forward pass, offering both flexibility and scalability. Extensive experiments across multiple tasks and settings demonstrate the effectiveness of our approach, highlighting its potential to support fast, versatile, and inclusive image customization. To the best of our knowledge, this work represents the first attempt to achieve such general-purpose, training-free personalization within diffusion models, paving the way for future research in personalized image generation.
