Abstract
Hairstyle transfer is challenging due to hair structure differences in the source and target hair. Latent Optimization of Hairstyles via Orthogonalization (LOHO) is an optimization-based approach using GAN inversion to infill missing hair structure details in latent space during hairstyle transfer. Hair is decomposed into three attributes: perceptual structure, appearance, and finer style, and includes tailored losses to model each of these attributes independently. Two-stage optimization and gradient orthogonalization enable disentangled latent space optimization of the three hair attributes. Using LOHO for latent space manipulation, users can synthesize novel photorealistic images by manipulating hair attributes either individually or jointly, transferring the desired attributes from reference hairstyles.
