Lenna (or Lena) is a standard test image used in the field of digital image processing, starting in 1973.[1] It is a picture of the Swedish model Lena Forsén, shot by photographer Dwight Hooker and cropped from the centerfold of the November 1972 issue of Playboy magazine. The image has attracted controversy in recent years because of its "inappropriate" subject matter,[2] and many journals have discouraged or banned its use.[3][4][5][6] Forsén herself has called for it to be retired, saying "It's time I retired from tech."[7]
The spelling "Lenna" came from the model's desire to encourage the proper pronunciation of her name. "I didn't want to be called Leena [English: /ˈliːnə/]," she explained.[8]
