Is that really effective? Just take some face detection code and have it learn what cat fur looks like instead.

- amix 18y agoIt's ok effective judging by my usages and I could just iterate over this solution if someone brute forced it or implemented a "cat fur detector" (which for my uses is pretty unrealistic). Battling spammers is really a battle where you implement better protections and they implement better attacks. The conclusion so far has been that it isn't possible to check-mate them - - and it's very unlikely it will ever happen as a lot of spammers use "human bots"... Using visual captcha is much more user friendly thought, so it's a win for the users.
- stevenrace 18y agoThere is actually a 'Google Tech Talk' on detecting cats (versus other shapes) from images: http://www.youtube.com/watch?v=-w72_VwSj6A http://www.youtube.com/watch?v=-w72_VwSj6A Is it really that easy? I would think flagging for texture would be difficult, as it's likely indistinguishable from noise (data, shadows, clothing..). Approximating shape/avg. contour is likely easier than looking for fur patterns. Any suggestions on books/papers/etc on image recognition?
