Lenna Test Image
Lenna image became a digital image processing icon despite its controversial origins
3 Feb 2026
0
Why has the Lenna image been discouraged or banned from use in recent years within the digital image processing community?
Because of concerns about its origin from a Playboy centerfold and issues of appropriateness and inclusivity.
Because the image quality is too low for modern image processing techniques.
Because it is copyrighted and cannot be legally used in research anymore.
