Title: Rohit Saha: Innovator in Hairstyle Transfer Technology

Introduction

Rohit Saha is a prominent inventor based in Toronto, Canada. He has made significant contributions to the field of hairstyle transfer technology. His innovative approach addresses the challenges associated with hair structure differences in source and target hairstyles.

Latest Patents

Rohit Saha holds a patent for "Style try-on with reverse GANs." This invention focuses on optimizing hairstyle transfer through an optimization-based approach using GAN inversion. The method, known as Latent Optimization of Hairstyles via Orthogonalization (LOHO), effectively infills missing hair structure details in latent space during the transfer process. The hair is decomposed into three attributes: perceptual structure, appearance, and finer style. Tailored losses are included to model each of these attributes independently. The two-stage optimization and gradient orthogonalization enable disentangled latent space optimization of the three hair attributes. This allows users to synthesize novel photorealistic images by manipulating hair attributes either individually or jointly, transferring the desired attributes from reference hairstyles.
