There’s been a lot of buzz lately around AI, “deep learning”, computer vision. It’s all to do with image recognition. Apple and Google have also been implementing it with their mobile operating systems to help categorise your shots. Facebook also does this, too, although it rarely makes itself obvious. It’ll often see faces, and ask if you want to tag somebody. Sometimes it’ll even recognise the person. But that’s about it.
Facebook actually looks at a whole lot more, though. If you want to go digging through page source, you can find this information out yourself. But, it’s a bit of a hassle. Now, a new Chrome extension overlays the information right on top of the image in your browser. While primarily intended for those who use screen readers, it does offer insight into how Facebook automatically reports or censors certain images.
