Why not use it to turn your selfies into harrowing but artistic portraits instead? The site uses an algorithm trained on 45,000 classical portraits to render your face in faux oil, watercolor, or ink. There's a huge number of styles included in this database, covering artists from Rembrandt to Titian to van Gogh, with each input producing a unique portrait. As the researchers point out, unlike earlier AI methods that created similar AI portraits, the algorithm here is not merely "painting over" your face in a new style. Instead, it uses what's known as a generative adversarial network (GAN) to generate new features from scratch.

With the internet buzzing about the viral FaceApp, which uses AI to predict how anyone will look in 30 years, there's another service that will transform you into a work of art. If you've ever dreamed of how your portrait would look if it were painted by one of the great masters, this app is for you. AI Portraits uses information from over 45,000 15th-century masterpieces to help "paint" the portrait of any photo that's uploaded. While there are plenty of apps and filters that promise to make your photo into a work of art, AI Portraits distinguishes itself with its GAN models. Many services use style transfers that alter colors, but leave the facial lines untouched.

When you visit the website "This Person Does Not Exist" you will likely see a face smiling back at you. Seems innocent enough -- until you realize the face is not actually real, but generated by a neural network algorithm. That person is not real. The website's neural network algorithm codes a "facial image from scratch from a 512 dimensional vector", according to Phillip Wang, who created and posted about it in a Facebook group on Feb. 12. Wang suggested he created the site to "raise awareness for what a talented group of researchers made at Nvidia over the course of 2 years," according to a post in Hacker News. The technology is based on a state of the art Nvidia-designed AI known as StyleGAN -- a neural network that can separate aspects of an image to learn and generate new images.

You might already know that AI can put real faces in implausible scenarios, but it's now clear that it can create faces that otherwise wouldn't exist. Developer Phillip Wang has created a website, ThisPersonDoesNotExist, that uses AI to generate a seemingly infinite variety of fake but plausible-looking faces. His tool uses an NVIDIA-designed generative adversarial network (where algorithms square off against each other to improve the quality of results) to craft faces using a large catalog of photos as training material. The results are imperfect (look at the area below the woman's eyes as proof), but when everything falls into place, it's disconcertingly realistic -- you sometimes wouldn't know a person is imaginary. It doesn't require much computational power, either.

With the help of artificial intelligence, you can manipulate video of public figures to say whatever you like -- or now, create images of people's faces that don't even exist. You can see this in action on a website called thispersondoesnotexist.com. It uses an algorithm to spit out a single image of a person's face, and for the most part, they look frighteningly real. Hit refresh in your browser, and the algorithm will generate a new face. Again, these people do not exist.

Let's Enhance is a new free website that uses neural networks to upscale your photos in a way Photoshop can't. It magically boosts and enhances your photo resolution like something straight out of CSI. The service is designed to be minimalist and extremely easy to use. The homepage invites you to drag and drop a photo into the center (once you do, you'll be asked to create a free account): Once it receives your photo, the neural network goes to work, upscaling your photo by 4x, removing JPEG artifacts, and "hallucinating" missing details and textures into your upscale photo to make it look natural. You'll need to wait a couple of minutes for the work to be done, but it's worth the wait -- the results we've seen are impressive.
