Solving CAPTCHAs using Probabilistic Programming (naviablog.wordpress.com) 11 points by bobicool 15y ago ↗ HN
[–] wladimir 15y ago ↗ Interesting article! I had a similar idea in one of my earlier captcha cracking approaches. For me, it had several problems:1) it was very hard to get the captcha generation exactly right, so that it is close enough to the algorithm of the original site2) comparing two generated images containing text meaningfully (in a noise tolarant way) is hardEventually I went with more regular computer vision techniques.It's nice to see that the approach is feasible with the right techniques :)
