  In this work, we target the task of text-driven style transfer in the context
of text-to-image (T2I) diffusion models. The main challenge is consistent
structure preservation while enabling effective style transfer effects. The
past approaches in this field directly concatenate the content and style
prompts for a prompt-level style injection, leading to unavoidable structure
distortions. In this work, we propose a novel solution to the text-driven style
transfer task, namely, Adaptive Style Incorporation~(ASI), to achieve
fine-grained feature-level style incorporation. It consists of the Siamese
Cross-Attention~(SiCA) to decouple the single-track cross-attention to a
dual-track structure to obtain separate content and style features, and the
Adaptive Content-Style Blending (AdaBlending) module to couple the content and
style information from a structure-consistent manner. Experimentally, our
method exhibits much better performance in both structure preservation and
stylized effects.
