This was the first time I ever encoun­tered this face-detection fea­ture, and it just so hap­pened Face­book picked a par­tic­u­larly poor photo to intro­duce it with!

Clearly they’ve started using a face-detection algo­rithm to pin­point prob­a­ble can­di­dates for tag­ging — unfor­tu­nately, the algo­rithm is eas­ily fooled by V for Vendetta masks. The photo in ques­tion fea­tures four friends and we have no idea who is whom — it was a few years ago and we’re all iden­ti­cally clothed!

Nice one, Face­book!
