Controlling Face's Frame generation in StyleGAN's latent space operations: Modifying faces to deceive our memory

Roca, Agustín, Britos, Nicolás Ignacio

Innocence Project is a non-profitable organization that works in reducing wrongful convictions. In collaboration with Laboratorio de Sue\~no y Memoria from Instituto Tecnol\'ogico de Buenos Aires (ITBA), they are studying human memory in the context of face identification. They have a strong hypothesis stating that human memory heavily relies in face's frame to recognize faces. If this is proved, it could mean that face recognition in police lineups couldn't be trusted, as they may lead to wrongful convictions. This study uses experiments in order to try to prove this using faces with different properties, such as eyes size, but maintaining its frame as much as possible. In this project, we continue the work from a previous project that provided the basic tool to generate realistic faces using StyleGAN2. We take a deep dive into the internals of this tool to make full use of StyleGAN2 functionalities, while also adding more features, such as modifying certain of its attributes, including mouth-opening or eye-opening. As the usage of this tool heavily relies on maintaining the face-frame, we develop a way to identify the face-frame of each image and a function to compare it to the output of the neural network after applying some operations. We conclude that the face-frame is maintained when modifying eye-opening or mouth opening. When modifying vertical face orientation, gender, age and smile, have a considerable impact on its frame variation. And finally, the horizontal face orientation shows a major impact on the face-frame. This way, the Lab may apply some operations being confident that the face-frame won't significantly change, making them viable to be used to deceive subjects' memories.


The Hidden Role of Facial Recognition Tech in Many Arrests

WIRED

In April 2018, Bronx public defender Kaitlin Jackson was assigned to represent a man accused of stealing a pair of socks from a TJ Maxx store. The man said he couldn't have stolen the socks because at the time the theft occurred, he was at a hospital about three-quarters of a mile away, where his son was born about an hour later. Jackson couldn't understand how police had identified and arrested her client months after the theft. She called the Bronx District Attorney's Office, and a prosecutor told her police had identified her client from a security camera photo using facial recognition. A security guard at the store, the only witness to the theft, later told an investigator from her office that police had sent him a mugshot of her client and asked in a text message "Is this the guy?" Jackson calls that tactic "as suggestive as you can get."


A Texas jury found him guilty of murder. A computer algorithm proved his innocence.

Nearly a decade into his life sentence for murder, Lydell Grant was escorted out of a Texas prison in November with his hands held high, free on bail, all thanks to DNA re-examined by a software program. "The last nine years, man, I felt like an animal in a cage," Grant, embracing his mother and brother, told the crush of reporters awaiting him in Houston. "Especially knowing that I didn't do it." Now, Grant, 42, is on a fast-track to exoneration after a judge recommended in December that Texas' highest criminal court vacate his conviction. His attorneys are hopeful a ruling is made in the coming weeks.


Ritsumeikan professor spearheads local Innocence Project to clear wrongfully convicted

The Japan Times

A university professor is heading the Japanese version of a U.S.-led movement to exonerate people who have been wrongfully charged and imprisoned using DNA testing. Mitsuyuki Inaba, 51, who is neither a lawyer nor an expert in criminal law, is a professor at Ritsumeikan University's College of Policy Science. He believes Japan's criminal justice system is rife with fundamental failures that lead to wrongful imprisonment due to the "unscientific" way in which investigations are carried out. Inaba, who specializes in cognitive science, took up the post of director at the Innocence Project Japan, which was launched in April in cooperation with lawyers and other legal experts. Similar movements have sprouted in Britain, South Africa and Taiwan.
