Stereograms & Lena

After posting that stereogram of a dinosaur I took a look at Google to see if I could find other interesting pictures. I found an interesting site (okay, that´s the first to appear in my search) named simply Stereogram Page with some useful information and stereograms. Although I suggest to look more pages if you became really interested in the matter, I found in the site an interesting picture (the one at the beginning of the post).

This picture is not interesting because of the beauty of the lady in the photo, but because that girl is Lena. I met Lena for the first time a couple of weeks ago in the room of another physicist. While he was talking to me about a work he´s doing on image treatment, he showed me a photo of a girl (just the face) and asked me if I knew her. I said I didn´t and he told me who she was and a little story.

The photo was one of Lena and he told me that the picture is extremely popular in the scientific community of image treatment but people didn´t know who was Lena untill someone decided to look for the first paper where the image appeared and asked the authors where they found the photo. They said they scanned it from an old Playboy magazine. These guys then tried to find her and they succeeded: she was already a sweet old grandmother. So, they took her to a congress on image treatment and she was extremely applauded. He told me the story and then showed me the original photo, full body. It´s sad I don´t have enough space to put it here... :o)
