The truth about Lena

lena
Everyone in image processing knows her face, but until today I could only speculate about what lay below the shoulder-line.

Lena is a standard test image used in image processing books, papers, and software tools. It's good for its mix of highly detailed areas, smooth areas, and sharp edges. She's also much more pleasant to look at than zone plates (argh! My eyes hurt again!), mandlebrot sets, or pictures of buildings. And as it turns out she's a Playboy model from the 70s who had no idea of her fame until she was invited to a computer graphics conference. I'll never look at test images quite the same way again.

Full story and details here.
