Diffusion-driven GAN Inversion for Multi-Modal Face Image Generation

1 code implementation CVPR 2024 Jihyun Kim, Changjae Oh, Hoseok Do, Soohyun Kim, Kwanghoon Sohn

To do this, we combine the strengths of Generative Adversarial networks (GANs) and diffusion models (DMs) by employing the multi-modal features in the DM into the latent space of the pre-trained GANs.
