Facebook’s computer vision tags cover multiple concepts including food, objects (e.g., eyeglasses), people’s expression (are they smiling?), sports, nature (sky, mountains), and more. The best part – if you are in a group photograph, Facebook can accurately tell you the exact number of people in the frame.
Chrome Extension that I hacked together in a few minutes to make it easy to see the tags that Facebook is automatically applying to you and your friends’ photos. Once you install it, all the photos you see on your Facebook timeline will automatically be overlaid with their tags
The goal is simply to make everyone aware of the kind of information that is routinely extracted from your own images today.
