Researchers at Adobe and UC Berkeley have developed an AI method that can detect whether faces in photos were manipulated using Adobe Photoshop’s Liquify Tool. The research team trained a Convolutional Neural Network (CNN) on thousands of portrait images on which Face Aware Liquify was applied using a Photoshop script.
In a series of subsequent experiments, the AI was able to correctly detect 99.4% of manipulated images, as compared to humans who were able to detect 53.5%. The AI was also able to identify which parts of the face were edited, and in some cases, it could “undo” a manipulation to reconstruct the original, unedited image.
