## Abstract (arXiv)

The exploration of the latent space in StyleGANs and GAN inversion exemplify impressive real-world image editing, yet the trade-off between reconstruction quality and editing quality remains an open problem. In this study, we revisit StyleGANs' hyperspherical prior Z and Z^+ and integrate them into seminal GAN inversion methods to improve editing quality. Besides faithful reconstruction, our extensions achieve sophisticated editing quality with the aid of the StyleGAN prior. We project the real images into the proposed space to obtain the inverted codes, by which we then move along Z+, enabling semantic editing without sacrificing image quality. Comprehensive experiments show that Z+ can replace the most commonly-used W, W+, and S spaces while preserving reconstruction quality, resulting in reduced distortion of edited images.
