Lenna Image

While she is not a student in our course, the Lenna (or Lena) picture is one of the most widely used standard test images. The comp.compression FAQ says the following:

For the curious: 'lena' or 'lenna' is a digitized Playboy centerfold, from November 1972. (Lenna is the spelling in Playboy, Lena is the Swedish spelling of the name.) Lena Soderberg (ne Sjööblom) was last reported living in her native Sweden, happily married with three kids and a job with the state liquor monopoly.
