selfiefilter

Google has announced a new set of "people-centered" design guidelines around the face-altering selfie filters built into many smartphone camera apps. The initiative encourages companies to be more transparent about how they apply these filters, change the design language used, and give users more direct control over their experience.

Snapchat's "lenses," more colloquially known as selfie filters or just "filters," may seem like a totally inane feature. But it turns out the facial recognition technology behind them is advanced, impressive... and a tad scary.
