Surrealism blooms through Pika

Check out this delightful demo:

Individual steps, as I understand them:

  • Generate image (in this example, using Google Imagen).
  • Apply background segmentation.
  • Synthesize a new background, and run what I think is a fine-tuned version of IC-Light (using Stable Diffusion) to relight the entire image, harmonizing foreground/background. Note that identity preservation (face shape, hair color, dress pattern, etc.) is very good but not perfect; see changes in the woman’s hair color, expression, and dress pattern.
  • Put the original & modified images into Pika, then describe the desired transformation (smooth transition, flowers growing, clouds moving, etc.).
