MultiDiffusion: Fusing Diffusion Paths for Controlled Image Generation

Bar-Tal, Omer, Yariv, Lior, Lipman, Yaron et al.

Understand

Recent advances in text-to-image generation with diffusion models present transformative capabilities in image quality.

  • However, user controllability of the generated image, and fast adaptation to new tasks still remains an open challenge, currently mostly addressed by costly and long re-training and fine-tuning or ad-hoc adaptations to specific image generation tasks.
  • In this work, we present MultiDiffusion, a unified framework that enables versatile and controllable image generation, using a pre-trained text-to-image diffusion model, without any further training or finetuning.
  • At the center of our approach is a new generation process, based on an optimization task that binds together multiple diffusion generation processes with a shared set of parameters or constraints.
