Apply Visual Style with Swapping Self-Attention

The "Apply Visual Style with Swapping Self-Attention" action allows you to transform an image by applying a predefined visual style using sophisticated techniques. This operation requires a depth image and a style image to perform the transformation effectively, leveraging a range of artistic styles.

  • Style Name: Choose from a predefined set of styles, such as "munch," "low-poly," "line-art," "van-gogh," and more. The default is set to "fire."
  • Diffusion Steps: An integer that defines the number of diffusion steps to process, with a default of 50.
  • Controlnet Scale: A number that sets the scale parameter for ControlNet, defaulting to 0.5.

Expected Output

The output will be a transformed image that reflects the chosen style applied to the original depth image. You can expect a URI link to the newly generated image, showcasing the artistic transformation.
