o before, “mean” prompt embeddings for both source and target concepts are created and finally the pix2pix-zero algorithm in combination with the “inverse” latents is used to edit the image.
Pix2Pix Zero is the first model that allows “zero-shot” image editing. This means that the model
can edit an image in less than a minute on a consumer GPU as shown here
As mentioned above, Pix2Pix Zero includes optimizing the latents (and not any of the UNe
