With so many fake pictures and information out there, we need a tool to figure out the truth now more than ever. Researchers Richard Zhang and Oliver Wang, in collaboration with the scientists Sheng-Yu Wang, Andrew Owens, and Alexei Efros from UC Berkeley takes the initiative to create a tool that spots manipulated faces edited using Photoshop’s Face Aware Liquify filter. It uses machine learning to detect if the images are manipulated.
The tool is designed around the Photoshop’s liquefy tool that is usually used to make alterations to the face shape and features. It is very commonly used by the photographers out there for their professional work. The changes made using Photoshop can be so brilliant that it makes it very challenging to differentiate between the true and a fake image.
The research after the created of the tool started out by showing image pairs of the original and the altered to people who knew about the alterations. The idea was that the tool had to perform better than the naked eye at identifying the alterations. While the people were able to identify the alterations 53% of the time, this tool was able to identify them 99% of the time and it also points out the affected areas and methods of face wrapping and hence is able to revert the images to their original form.
The company doesn’t have any immediate plans of commercialising the tool but intends to do further research on it. It considers the tool one of many “efforts across Adobe to better detect image, video, audio and document manipulations.”
“While we are proud of the impact that Photoshop and Adobe’s other creative tools have made on the world, we also recognize the ethical implications of our technology,” the company says in a blog post. With all the fake information spreading out there, there is a need of this tool to detect it to control it.
“Trust in what we see is increasingly important in a world where image editing has become ubiquitous,” it adds. “Fake content is a serious and increasingly pressing issue.”
Adobe has clearly taken the concern of fake information on the internet very seriously as it released another tool last year to detect media editing done by cloning, splicing and removing objects.
