High-fidelity GAN Inversion with Padding Space

Bai, Qingyan, Xu, Yinghao, Zhu, Jiapeng et al.

Understand

Inverting a Generative Adversarial Network (GAN) facilitates a wide range of image editing tasks using pre-trained generators.

  • Existing methods typically employ the latent space of GANs as the inversion space yet observe the insufficient recovery of spatial details.
  • In this work, we propose to involve the padding space of the generator to complement the latent space with spatial information.
  • Concretely, we replace the constant padding (e.g., usually zeros) used in convolution layers with some instance-aware coefficients.
