Abstract

In embodiments, computer systems and methods provide a hairstyle VTO experience. A generative artificial intelligence (Gen AI) model (e.g. a diffusion-based model and a conditioning network) configured to generate output images in response to spatial conditioning is invoked with a plurality of conditioning images to condition the generation of the new hairstyle on an image of the face. The conditioning images comprise a hairstyle mask to control a shape of the new hairstyle; and an edge detection result image to guide a structure of the new hairstyle. The hairstyle mask and edge detection result are obtained from a 3D model of a sample hairstyle. The mask is aligned with a pose of the face, for example, determined from a face mesh generated for the face. The image of the face is preprocessed to remove an existing hairstyle (e.g. using a dilated hair mask and inpainting).
