Detecting Computer Generated Faces

Schneier points us to this effort, detecting artificial human faces.  Technical details interesting. 

A way to spot computer-generated faces   by Bob Yirka , Tech Xplore

Anatomy structures of a human eye. Bottom: Examples of pupils of real human (left) and GAN-generated (right). Note that the pupils for the real eyes have a strong circular or elliptical shapes (yellow) while those for the GANgenerated pupils are with irregular shapes (red). And also the shapes of both pupils are very different from each other in the GAN-generated face image. Credit: arXiv:2109.00162v1 [cs.CV]

A small team of researchers from The State University of New York at Albany, the State University of New York at Buffalo and Keya Medical has found a common flaw in computer-generated faces by which they can be identified. The group has written a paper describing their findings and have uploaded them to the arXiv preprint server.
