But with the threat of image and video fakery quickly reaching epic proportions (think deepfakes and face swapping), fake content, images and videos are becoming a major issue. Photoshop's in-built "Face Aware Liquify" tool was used to edit the facial features of thousands of images scraped from the internet using a Photoshop script. This research focuses on Face Aware Liquify because it's a popular way to adjust faces. "This element of human creativity broadened the range of alterations and techniques used for the test set beyond those synthetically generated images", Adobe says.

Researchers believe that by using a deep learning method called a convolutional neural network (CNN), it will be able to recognise faces that have been manipulated. The images were sourced from the internet and then either passed through Liquify for adjustment or given to an artist for manual enhancement.

The researchers trained the AI system by feeding data on original and altered content.

On testing, it was found that while human eyes were able to judge the altered face 53 per cent of the time, the the trained neural network tool achieved results as high as 99 per cent. Additionally, the tool could revert back to the original state of the edited image and although it wasn't 100 percent accurate, it was good enough to impress the researchers. To that end, Adobe researchers Richard Zhang and Oliver Wang worked with a UC Berkeley team consisting of Sheng-Yu Wang, Dr. Andrew Owens, and Professor Alexei A. Efros to develop an AI for spotting face manipulation.

Most of the victims had suffered a sudden loss of glucose in their blood, health official Ashok Kumar Singh told AFP news agency. Several years ago, United States researchers had said the brain disease could be linked to a toxic substance found in the fruit.

"That is the most important step in with the ability to detect certain forms of image modifying, and the undo capacity works strangely well".

"This new analysis is a part of a broader attempt across Adobe to better discover image, video, audio, and document manipulations", the corporate wrote in a blog post on Friday.

"Adobe is firmly committed to finding the most useful and responsible ways to bring new technologies to life - continually exploring using new technologies, such as artificial intelligence (AI), to increase trust and authority in digital media", Adobe concludes.
