Stabilized Temporal 3D Face Alignment Using Landmark Displacement Learning

S Lee, H Yoon, S Park, S Lee, J Kang - Electronics, 2023 - mdpi.com
One of the most crucial aspects of 3D facial models is facial reconstruction. However, it is
unclear if face shape distortion is caused by identity or expression when the 3D morphable …

Local spherical harmonics for facial shape and albedo estimation

S Heo, H Song, J Kang, S Lee - IEEE Access, 2020 - ieeexplore.ieee.org
In this paper, we present a novel facial albedo and 3D shape recovery method with a local
spherical harmonic illumination model. From a face in an image, the proposed method can …

Unlocking Potential of 3D-aware GAN for More Expressive Face Generation

J Hwang, J Kang, K Lee, S Lee - Proceedings of the 2023 ACM …, 2023 - dl.acm.org
As style-based image generators have achieved disentanglement in features by converting
latent vector space to style vector space, numerous efforts have been made to enhance the …
