LinkGAN: Linking GAN Latents to Pixels for Controllable Image Synthesis

Figure: Concept diagram of LinkGAN, where some axes of the latent space are \textit{explicitly} linked to the image pixels of a spatial area. In this way, we can alter the image content within the linked region simply by resampling the latent code on these axes.

Figure: Precise local control achieved by LinkGAN on 2D image synthesis, like StyleGAN2 (left three columns), and 3D-aware image synthesis, like EG3D (right two columns). It is noteworthy that, under the 3D-aware case, we can control both the appearance and the underlying geometry.

[Paper] [Project Page]

In the repository, we propose LinkGAN to explicitly link some latent axes to a region of an image or a semantic via an easy-to-implement yet powerful regularizer. Building such a connection facilitates a more convenient local control of GAN generation, where users can alter the image content within a spatial area simply by partially resampling the latent codes. Extensive experiments on 2D image synthesis (e.g., StyleGAN2) and 3D-aware image synthesis (e.g., EG3D) demonstrate the effectiveness of our proposed method.
