Publication number: 20240169682Abstract: Aspects of the invention include techniques for intimacy-based masking of three dimensional (3D) face landmarks within a metaverse. A non-limiting example method includes determining a degree of intimacy R between a first user and a second user responsive to a first avatar of the first user being observed by a second avatar of the second user in a virtual environment. An initial set of M landmarks of a feature of the first avatar is determined and N landmarks are randomly selected from M for masking. The N landmarks are replaced with random noise sampled with a unit normal distribution to define a set of noised landmarks X that are then iteratively denoised to define a set of denoised landmarks D. A masked version of the first avatar is presented to the second user by modifying the feature of the first avatar with the set of denoised landmarks D.Type: ApplicationFiled: November 21, 2022Publication date: May 23, 2024Inventors: Xiao Feng Ji, Yu Hong Li, Jian Jun Wang, Yuan Jin, Li ping Wang
