I’m not sure.
Perhaps getting computer vision that’s reliably better than humans costs a lot of money that a project like OpenStreetMap doesn’t have?
Comment on FOSDEM 2025 - MapTCHA, the open source CAPTCHA that improves OpenStreetMap
adespoton@lemmy.ca 1 year agoThe big question though is: why?
CAPTCHA was implemented because machine learning was worse than people at solving the problems, so they could filter out the bots AND train their algorithms.
Today, the bots are often better than the humans, so both reasons for having CAPTCHAS no longer make sense. Even user verification can be easily faked by AI now.

Could be… it makes sense to reinvent the wheel if the previous inventors won’t share.

They explain it in the video. They already use algorithms to detect if things are buildings or not.
But if their algorithm can’t make a determination or is uncertain below a certain threshold, they send it to Maptcha to get a bulk human opinion.
