Disentangled Stylized Image Generation via IP-Cross-Attention Rearrangement

원문 초록

With a solid theoretical foundation and pretraining on large-scale datasets, diffusion-based methods have achieved controllable generation leveraging text and image conditions, and generating excellent stylized images is possible using diffusion models. However, previous methods face significant challenges. First, because diffusion generation is iterative, the common approach of learning implicit style representations via cycle-consistency strategies is too costly and not well-suited to diffusion, even for LoRA-based methods. Second, decoupling style is difficult in the latent space of diffusion models. Representations of attributes are coupled in the latent space of diffusion models; thus, extracting style attributes with diffusion models usually suffers from the issue of content leakage. Furthermore, because style is hard to represent in natural language, capturing style using text prompts or textual inversion is deficient. In this paper, we propose a method for achieving disentangled stylized image generation through IP-cross-attention rearrangement, based on our experimental observations. We also propose negative content guidance, inspired by classifier-free guidance, to reduce content leakage in stylized image generation.
