Mediawiki does not need a person to check it live, it has users that are reviewing the changes anyway. It would be nice to have a *simple* way to put people down and have them label images, I could find people if it was really simple. Right now it is not really simple. Most people just dont have the concentration to read the docs or learn how to use the wiki. mike ___ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l

Re: [Wikitech-l] Using computer vision to categorize images at Commons
I looked at perceptual hashing some time ago. A problem was that it had to keep the uncompressed image in memory, and it was slow for being applied on commons scale. ___ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
Re: [Wikitech-l] Using computer vision to categorize images at Commons
Hi Maarten; I think that this is a perfect example of open question in wiki research. WikiPapers has a page for that stuff.[1] Can you add some bits there about this? I dind't know about OpenCV, I will check it for sure, and I will try to something (I'm a bot developer).

It might also be possible to do other fun searches, like looking for watermarks or poorly rotated photos (without the EXIF data, I guess) or making/breaking CAPTCHAs or... I wonder if facial recognition will soon need to have some kind of opt-out.

I have found a tutorial for Python coders http://creatingwithcode.com/howto/face-detection-in-static-images-with-python/After some tests, it works fine (including René Descartes face : )). This is going to be very helpful to improve Images for biographies accuracy http://toolserver.org/~emijrp/imagesforbio/ 2012/2/20 emijrp emi...@gmail.com Hi Maarten; I think that this is a perfect example of open question in wiki research.
