>Please note that we no longer distribute the following images that were previously available in our database: 4.2.04 (lena), 4.2.02 (tiffany), elaine.512, numbers.512 and testpat.1k. Although these images have played a significant role in the history of image processing, they no longer represent the best examples for future research.
What are the reasons for not distributing anymore the other ones?
Took a look at them in Wayback, and the images of other women look similarly styled (could be other models?), and the numbers and testpat images use the Lena image as part of them.
Yep, thanks, still we don't know if it was because they are (now) considered somehow offensive of women or if it was because (even if protection was not enforced) they are copyrighted.
Or simply because they were sourced from Playboy magazine (which in itself is now deemed ethically questionable).
The statement on the page seems to me meaningless:
> they no longer represent the best examples for future research.
without the actual reason why they "no longer represent", which BTW implies that for some time (30 or 40 years + ) they actually were "the best examples".
