Facebook takes to facial recognition to identify friends

San Francisco: Facebook has gone on to enhance its face detection feature, launched in July, and has come up with a new feature called "tag suggestions". The new feature makes use of face recognition technology to suggest which friend is probably featured in which photo.

How it works is, say you have uploaded a huge number of photographs, Facebook will group together the faces that look similar, based on the premise that they are photos of the same person. Facebook also goes and looks into the past photo tags and suggests who in the picture.Facebook believes the new feature will simplify the process of photo sharing. Also for users who want to maintain their privacy and not have their name suggested, they can use the privacy settings of the site and turn off the feature.

The earlier face detection feature allowed users to only tag the photos and not suggest the faces. The feature will start off in U.S. in the weeks to come.
