  • $$E^{3}DGE$$: Self-Supervised Geometry-Aware Encoder for Style-Based 3D GAN Inversion

    Yushi Lan, Xuyi Meng, Shuai Yang, Chen Change Loy, Bo Dai

    International Journal of Computer Vision · 2025

    This paper addresses the challenge of 3D GAN inversion, focusing on predicting a latent code from a single 2D image to faithfully recover 3D shapes and textures, and introduces an efficient self-training scheme that does not rely on real-world 2D-3D pairs but instead utilizes proxy samples generated from a 3D GAN.
