Few were born to make good pictorial or photographic portraits, but if the "steady hand" is an artificial intelligence, it can be achieved.
Massless Media API created a tool called “FaceMaker AI” which instantly transforms the scribble of a face (one of those shameful things done with Paint) into “almost” photorealistic face portraits.

The key word is "almost", because as has happened to similar systems in the past, it sometimes produces bizarre results. The human portraits produced sometimes feature strange elements such as deformed eyes or strange haircuts that a barber wouldn't think twice about taking out.
A Picasso in a box: AI portraits
For making portraits simply draw in the app canvas. There is only a few small precautions to take: follow the color corresponding to each facial feature. Red for the face, blue for the hair, light brown for the left eye, and dark brown for the right eye. You can even design earrings or a necklace to adorn your portrait models with AI jewelry :)
Jack Cohen, co-founder of massless, says Face Maker AI is created to be a "free educational tool to demonstrate the potential of GANs (Adversary Generative Networks: if you don't know what they are, find here a post by Futuroprossimo).
Either way, transform the Sketching into artwork and portraits isn't exactly new in the world of AI, but there's always room for exploration. Recently, artificial intelligence was even trained to produce and cross-reference tens of thousands of portraits of people from scratch… that do not exist.
What will be the next step? Portraits starting from simple descriptions, I'll tell you. "Computer! Show me the face of a dark person, with light eyes and a prominent nose." You'll see.
