Recent progress in personalized image generation using diffusion models has been significant. However, development in the area of open-domain and non-fine-tuning personalized image generation is proceeding rather slowly. In this paper, we propose Subject-Diffusion, a novel open-domain personalized image generation model that, in addition to not requiring test-time fine-tuning, also only requires a single reference image to support personalized generation of single- or multi-subject in any domain. Firstly, we construct an automatic data labeling tool and use the LAION-Aesthetics dataset to construct a large-scale dataset consisting of 76M images and their corresponding subject detection bounding boxes, segmentation masks and text descriptions. Secondly, we design a new unified framework that combines text and image semantics by incorporating coarse location and fine-grained reference image control to maximize subject fidelity and generalization. Furthermore, we also adopt an attention control mechanism to support multi-subject generation. Extensive qualitative and quantitative results demonstrate that our method outperforms other SOTA frameworks in single, multiple, and human customized image generation.

我们提出了一种新的开放域个性化图像生成模型Subject-Diffusion，它不需要测试时微调，只需要一个参考图像就能在任何领域中支持个性化生成单一或多个主体。我们通过构建自动数据标注工具和使用LAION-Aesthetics数据集，构建了一个包含7600万图像及其对应主体检测边界框、分割掩模和文本描述的大规模数据集。我们设计了一个新的统一框架，通过融合文本和图像语义，并结合粗粒度位置和细粒度参考图像控制，以最大化主体的准确性和一般化能力。此外，我们还采用了一种注意力控制机制来支持多主体生成。大量的定性和定量结果表明，我们的方法在单一、多个和人类定制的图像生成方面优于其他最先进的框架。请参考我们的项目页面。
