The results are so realistic in more than 90% of cases that it is difficult to doubt the credibility of the images

When looking at the photos on ThisPersonDoNotExist, it is hard to believe that these images are fake, and initially imagine that they are a database of persons who may be wanted for justice, for example, but developer Phil Wang confirmed that these faces are fake and do not actually exist.

These seemingly realistic and impressive faces (fake images) were created directly by computer. It can be said more accurately that two networks of neural algorithms are linked to each other, and are constantly trained by images of real people.

The process of falsifying images begins with a single neural network calculating all possible human characteristics, which are preserved during learning, from facial forms to skin characteristics and eye colors to hairstyles.

In doing so, completely new faces are created, after which the other neural network analyzes the result through experimental values, and if the fake face passes the « reality check », it is shown in its final form, and if the test is not passed it will be returned to the first neural network to modify it.

Realistic results

The results appear so realistic in more than 90% of cases that no one will doubt the credibility of the image as long as it does not know how it was created. Some defects may appear in fake faces, for example, there may be an error in facial consistency or skin structure, or transition areas may appear in the background.

There are many other projects that bring facial vitality, such as altered Qualia, where faces begin to smile before hiding them with the next face, as well as eye tracking and mouse-pointing, and there are many interesting examples on the AI portal’s home page.

The social network Twitter is currently full of countless images of artificial intelligence, where the company provides the user with the possibility to bring the image of faces that are uploaded with the movement of the head, eyes and smile as well, and this technique is known as « Deep Nostalgia », and works realistically and well with the faces of paintings and sculptures.
