From Kathi Reid's Ancestor Search Blog at http://ancestorsearch.blogspot.com/2009/08/how-google-picasa-face-recognition.html:
"Google Picasa Web Albums has face recognition software that can help name the unknown people who are in your old family photos.
"This free software even recognizes the same person at different ages."
The article goes on to describe how the author uploaded a group of pictures to Picasa and then wrote:
"It was a very impressive moment when Picasa presented me with a large array of photos with the same face, and then suggested a name which turned out to be correct. I can't begin to say how helpful this was in naming people in my old family photographs."
