While there has been significant progress in customizing text-to-image generation models, generating images that combine multiple personalized concepts remains challenging. In this work, we introduce Concept Weaver, a method for composing customized text-to-image diffusion models at inference time. Specifically, the method breaks the process into two steps: creating a template image aligned with the semantics of input prompts, and then personalizing the template using a concept fusion strategy. The fusion strategy incorporates the appearance of the target concepts into the template image while retaining its structural details. The results indicate that our method can generate multiple custom concepts with higher identity fidelity compared to alternative approaches. Furthermore, the method is shown to seamlessly handle more than two concepts and closely follow the semantic meaning of the input prompt without blending appearances across different subjects.

该论文介绍了一种在推导阶段用于组合定制化的文本到图像扩散模型的方法——Concept Weaver。该方法将过程分为两个步骤：创建与输入提示语义对齐的模板图像，然后使用概念融合策略个性化该模板。研究结果表明，与替代方法相比，我们的方法能够生成具有较高身份保真度的多个定制概念。此外，该方法能够无缝处理多个概念，并且在紧密遵循输入提示的语义含义时不会混合不同主题的外观。
