This manipulation creates entire non-existent face images. The table below summarises the main publicly available databases for research on detection of image manipulation techniques relying on entire face synthesis. Four different databases are of relevance here, all of them based on the same GAN architectures: ProGAN and StyleGAN. It is interesting to remark that each fake image may be characterised by a specific GAN fingerprint just like natural images are identified by a device-based fingerprint. In fact, these fingerprints seem to be dependent not only of the GAN architecture, but also of the different instances of it.
