Breakthrough in the detection of fake photos
With the rise of catfishing, US developers worked out the way to learn that a photo was photoshopped. Also, by calculating the optical flow between the original and the retouched pics, the algorithm can recreate the original image.
The development of algorithms for image processing has led to the fact that they have been used to create extremely realistic fake photos. For example, algorithms that are collectively called deepfakes in which person’s faces were realistically replaced by others had confused many people.
Such technologies have caused a wide fear, as a result of which some large Internet services like Pornhub have banned content of this type, and researchers have focused on creating protection against fakes.

In their work, the developers at the University of California at Berkeley and Adobe, led by Alexei Efros, created an algorithm for determining the change of the face in a photo using the popular graphics editor Adobe Photoshop.
The algorithm consists of two main parts: AI that recognizes edited images and that identifies areas that have been edited and then trained in the dataset created by the authors, consisting of almost a million source and edited images.

Moreover, the main feature of the application is that the developers taught the algorithm to determine exactly how the image was edited and even restore the original image.
They demonstrated this feature but noted that the reconstructed photo does not completely repeat the original one.
