MS-Diffusion: Multi-subject Zero-shot Image Personalization with Layout Guidance
This addresses the challenge of multi-subject personalization in text-to-image generation for applications like creative design, but it is incremental as it builds on existing diffusion models.
The paper tackles the problem of generating personalized images with multiple subjects from text prompts by introducing the MS-Diffusion framework, which uses layout guidance to maintain subject details and achieve cohesive compositions, resulting in improved image and text fidelity compared to existing models.
Recent advancements in text-to-image generation models have dramatically enhanced the generation of photorealistic images from textual prompts, leading to an increased interest in personalized text-to-image applications, particularly in multi-subject scenarios. However, these advances are hindered by two main challenges: firstly, the need to accurately maintain the details of each referenced subject in accordance with the textual descriptions; and secondly, the difficulty in achieving a cohesive representation of multiple subjects in a single image without introducing inconsistencies. To address these concerns, our research introduces the MS-Diffusion framework for layout-guided zero-shot image personalization with multi-subjects. This innovative approach integrates grounding tokens with the feature resampler to maintain detail fidelity among subjects. With the layout guidance, MS-Diffusion further improves the cross-attention to adapt to the multi-subject inputs, ensuring that each subject condition acts on specific areas. The proposed multi-subject cross-attention orchestrates harmonious inter-subject compositions while preserving the control of texts. Comprehensive quantitative and qualitative experiments affirm that this method surpasses existing models in both image and text fidelity, promoting the development of personalized text-to-image generation.
