Specific modern technical issues with the original scan are: Lena contains about 250,000 pixels, some 32 times smaller than a picture snapped with an iPhone 6. And then there’s a quality problem: The most commonly used version of the image is a scan of a printed page. The printing process doesn’t produce a continuous image, but rather a series of dots that trick your eye into seeing continuous tones and colors. Those dots, Acton says, mean that the scanned Lena image isn’t comparable to photos produced by modern digital cameras. and: [..] Scott Acton, the current editor of IEEE Transactions…

I feel that whenever Lena is mentioned, we should also give a shoutout to the researchers who were fed up with her and decided to use Fabio instead. https://arxiv.org/abs/1202.6429 What do you guys (yes, guys) think about making Fabio the standard image instead?

This paper uses Fabio instead of Lena for that reason: http://arxiv.org/abs/1202.6429

Two female image processing researchers recently used a picture of Fabio as a test image in a paper of theirs: http://arxiv.org/abs/1202.6429 (Additional discussion at http://www.kitware.com/blog/home/post/246) Personally, I'm all for the use of amusing (arousing?) test images, as long as they exhibit features that actually make for a good test image (a mix of flat and textured regions, sharp boundaries, etc.).
