The social network Facebook is currently developing and testing a new application that can detect faces in albums. This is a new technology for detecting faces in photo albums and is the first of a series of new applications related photos.

The aim of this new tool is to reduce the annoy of putting 'tags' in the photos to mark each of your friends, becaause if you have an album with plenty of photos or lots of friends in the same photo, the process is slow and inefficient.

To resolve this problem, Facebook implemented a facial detection technology that identifies and selects faces in photos, and the user only has to answer one question: 'Who is this guy? ".

This is the same technology used by most digital cameras. And so, despite this tool is not new, is an intelligent and effective improvement in the applications of social network.
