Abstract

A computer system obtains a digital source image of a human subject; determines a region to be modified in the source image; obtains descriptive text for the source image, including one or more attributes of the human subject depicted in the source image; generates a prompt that includes a modified version of the attribute (s) of the human subject; provides the source image, a representation of the region to be modified, and the prompt to a generative AI model (e.g., a text-to-image model comprising a diffusion model); and receives a modified image (e.g., an anonymized image) from the generative AI model including modified image content (e.g., generative in-painting produced by a diffusion model) in the region. The modified image is based on the source image and the modified version of the attribute(s) of the human subject.
