The subject technology receives an input image and a segmentation mask of the input image. The subject technology obtains reconstructed noise of the input image using the input image and the segmentation mask. The subject technology determines a first set of features by performing a first portion of a forward pass of the reconstructed noise through a decoder. The subject technology determines a second set of features by processing the input image for stable diffusion using an image to image (IMG2IMG) model. The subject technology generates a third set of features based on combining, using the segmentation mask, the first set of features and the second set of features with the reconstructed noise. The subject technology generates an output image by performing a remaining portion of the forward pass of the third set of features through the decoder.

Face identity preservation for image-to-image models using stable diffusion generative model

Embodiments enable virtual hair generation. The virtual hair generation can be performed by generating a first image of a face using a GAN model, applying 3D virtual hair on the first image to generate a second image with 3D virtual hair, projecting the second image with 3D virtual hair into a GAN latent space to generate a third image with virtual hair, performing a blend of the virtual hair with the first image of the face to generate a new image with new virtual hair that corresponds to the 3D virtual hair, training a neural network that receives the second image with the 3D virtual hair and provides an output image with virtual hair, and generating using the trained neural network, a particular output image with hair based on a particular input image with 3D virtual hair.
