How wonderful would it be if we had a software solution that automatically identifies names of people from a bunch of digital photographs? Well, you now have a solution, thanks to Google, which owns Picasa.
Picasa makes use of advanced face recognition technology to scan photographs for faces, and then groups these photographs as different sets of people.
So, once you tag the name of a person in a photograph, Picasa has the ability to automatically identify the person across different photographs. It is then our task to confirm the names against the photographs that it guesses. So, when you have a massive set of photographs located across your hard disk drive or on the web, Picasa can present a huge list of photographs with the same face, and you can confirm and label them all with a single click.
