Blended Diffusion for Text-driven Editing of Natural Images

Avrahami, Omri, Lischinski, Dani, Fried, Ohad

Understand

Natural language offers a highly intuitive interface for image editing.

  • In this paper, we introduce the first solution for performing local (region-based) edits in generic natural images, based on a natural language description along with an ROI mask.
  • We achieve our goal by leveraging and combining a pretrained language-image model (CLIP), to steer the edit towards a user-provided text prompt, with a denoising diffusion probabilistic model (DDPM) to generate natural-looking results.
  • To seamlessly fuse the edited region with the unchanged parts of the image, we spatially blend noised versions of the input image with the local text-guided diffusion latent at a progression of noise levels.
