Nice explanation, but do we still need to use Playboy for reference images?

Conversely, where is the actual Lena reference image? 8-bit pixel depth, 512x512, uncompressed tiff format preferably. Is there a canonical persistent URI someplace?

  Yes, the "Lenna Story" website: http://www.lenna.org/ http://www.lenna.org/ A permanent link to the TIFF image itself is: http://www.lenna.org/lena_std.tif http://www.lenna.org/lena_std.tif

  Only sort of. Since the image has been in use since before web services etc., more than one different copy was used as "canonical" so it's sort of unsolvable if you want to reproduce work. There has been more recent efforts to pick a reference one, as linked in this thread.

    Reply within a hour, thnx hn ;) Intrigue. Looks like it was removed from the SIPI db? https://sipi.usc.edu/database/database.php?volume=misc https://sipi.usc.edu/database/database.php?volume=misc World needs a new 600 DPI reference scan. To the Playboy Archives!

It's just a nude, grow up. And the image used in compression benchmarks only shows her face.

  It's interesting that there's so much resistance to stop using this particular image when there are billions of alternatives out there. Lena Forsén herself has asked that people stop using it, which seems like a pretty reasonable request.

    That is indeed a reasonable request. Do you have the source?
