Creating avatars. Whos got time for it?! Computers, thats who. Youll never have to waste another second selecting your hair style, skin tone or facial hair length if this research from Facebook finds its way into product form.

In a paper (PDF) presented at the International Conference on Computer Vision, Lior Wolf et al. show how they created a machine learning system that creates the best possible match of your real face to one in a custom emoji generator.

You may be thinking: Wait, didnt Google do this earlier in the year? Yes, kind of. But theres a critical difference. Googles version, while cool, used humans to rate and describe various features found in common among various faces: curly hair, nose types, eye shapes. These were then illustrated (quite well, I thought) as representations of that particular feature.

Essentially, the computer looks for the tell-tale signs of a feature like freckles, then grabs the corresponding piece of art from its database. It works, but its largely reliant on human input for defining the features.

Facebooks approach was different. The idea being pursued was a system that really makes the best possible representation of a given face, using whatever tools it has at hand. So whether its emoji, Bitmoji (shudder), Mii, a VR face generator or anything else, it could still accomplish its task. To paraphrase the researchers, humans do it all the time, so why not AI?
