Lena Forsén[1] (Swedish: [leːˈna fʊˈʂeːn]), previously Soderberg[2] (born Sjööblom;[2] born 31 March 1951), is a Swedish model who appeared as a Playmate in the November 1972 issue of Playboy magazine,[3] as Lenna Sjööblom. Her centerfold was photographed by Dwight Hooker. The image would later become a ubiquitous standard test image in the field of digital image processing, where the image is known as Lenna.

      For those who don’t get the joke, a cropped version of this image (LENA.BMP, 512x512 pixels) was for many years the deFacto standard for testing image processing algorithms. “Lena” has appeared in literally thousands of pages in image processing journals, usually in “original” and “processed” versions.
