DURBAN – Due to the Facebook outage, users of the social network were given a peek behind the digital curtain, with a number of images on the site replaced with the tags they have been assigned by Facebook's machine vision system according to The Verge.
During the outage when people where scrolling through their pictures instead of seeing pictures of a holiday or pictures of food, the users would just see text saying things like image may concern: people smiling, people dancing or wedding.
The sane image tags were shown on Instagram and as well as detailing of the general scene and object descriptions which suggest who is in a photo based on Facebook's facial recognition. (Facebook has been doing this for photos that a person is not tagged in since 2017).
Facebook has also been using machine learning to "read" images in this way since at least April 2016 and the project is a big part of the social giant's accessibility efforts.
The tags are used to provide a description of the photos and videos to users with sight impairments.
