Excerpt from Wikipedia

Figure artificially Swedish model Lena Söderberg (Lena Söderberg), in 1997, invited to attend the Annual General Meeting of the Society for Imaging Science. The picture was taken by the "Playboy" magazine photographer Dwight Hooker.

Now British Culture name was widely used"Lenna" was originally named when the "Playboy" magazine published this photo, to facilitate the approximate English readers correctly read Swedish "Lena" pronunciation.

Lenna standard image compression algorithm is the most widely used test chart- Her face and bare shoulder has become a de facto industry standard. However, the use of this image has also caused some controversy. Some people worry about its sexual content; "Playboy" magazine had threatened to sue the use of Lenna unauthorized. But the magazine has given up this threat, instead of encouraging the public interest because of the use of Lenna.

Editor of "IEEE Transactions on Image Processing" (IEEE Transactions on Image Processing) · C · David Monson (David C. Munson), in January 1996, cites two reasons for Ming Laina map popular in the field of scientific research the reason:

First of all, the picture contains a good flat areas, shadows and textures and other details, which are beneficial to test a variety of different image processing algorithms. It is a good test photos! Secondly, because this is a very attractive woman in the photo. Therefore, the majority made up of men tend to use the image processing industry research they consider attractive picture, it is not surprising.

Coincidentally, the "Playboy" magazine declared magazine that period is their best ever sales, has sold7,161,516 copies.

IEEE Professional Communication Society in May 2001 newsletter Jamie Hutchinson wrote in an article describes the history of this picture:

Alexander Sawchuk is estimated to be about between June 1973 or July, when he was an assistant at USC Signal and Image Processing Institute (SIPI), when he was a graduate student and a manager with SIPI lab is hurry to find a high-quality images for the University of conference papers. They do not like the general view of the television standard test used in the early 1960s used, they hope to find a glossy image can be a good dynamic range, and hope to have a facial image. Just then, it happened to someone walked in and took a recent issue of "Playboy." To be able to put on the light drum Muirhead illustration wired fax scanner, engineers ripped out one-third of the illustration above. At that time the scanner is equipped with analog to digital converter (red, green, and blue channels are equipped with a), and a Hewlett-Packard 2100 minicomputer. Muirhead 100LPI resolution is fixed, and engineers want to give an image of 512 × 512, so they will set a scan range in an upper portion of 5.12 inches, which is just to cut the shoulder position of the character.

Lenna is not the first piece of "Playboy" magazine Photos are representative of image processing algorithms. Lawrence G. Roberts in 1961 in his master's thesis about the image shake elapsed permission to use the picture magazine "Playboy," a 1960.
