• Abstract: StyleGAN2 is a state-of-the-art network in generating realistic images. Besides, it was explicitly trained to have disentangled directions in latent space, which allows efficient image manipulation by varying latent factors. Editing existing images requires embedding a given image into the latent space of StyleGAN2. Latent code optimization via backpropagation is commonly used for qualitative embedding of real world images, although it is prohibitively slow for many applications. We propose a way to distill a particular image manipulation of StyleGAN2 into image-to-image network trained in paired way. The resulting pipeline is an alternative to existing GANs, trained on unpaired data. We provide results of human faces' transformation: gender swap, aging/rejuvenation, style transfer and image morphing. We show that the quality of generation using our method is comparable to StyleGAN2 backpropagation and current state-of-the-art methods in these particular tasks.

  StyleGAN2 was demonstrated to be a powerful image generation engine that supports semantic editing. We present a per-image optimization method that tunes a StyleGAN2 generator such that it achieves a local edit to the generator's weights. Our experiments show a sizable gap in performance over the current state of the art in this very active domain.

  When common neural style transfer methods are used, the textures and colors in the style image are usually transferred imperfectly to the content image. This paper proposes a novel saliency constrained method to reduce or avoid such effects. The experiments show that the saliency maps of source images can help find the correct matching and avoid artifacts.

Next, we describe a latent mapper that infers a text-guided latent manipulation step for a given input image, allowing faster and more stable text-based manipulation.
