In this work, we argue that the GAN inversion task is required not only to reconstruct the target image by pixel values, but also to keep the inverted code in the semantic domain of the original latent space of well-trained GANs. For this purpose, we propose In-Domain GAN inversion (IDInvert) by first training a novel domain-guided encoder which is able to produce in-domain latent code, and then performing domain-regularized optimization which involves the encoder as a regularizer to land the code inside the latent space when being finetuned. The in-domain codes produced by IDInvert enable high-quality real image editing with fixed GAN models.
