Captcha.....

Name: Anonymous 2010-07-26 10:23

What's the percentage of success of the contemporary captcha visual encoders?

I thought I would try to implement one myself in JAVA.

Any advise appreciated!

The place for you is /comp/. No, really. It's meant for "how do I computer?" stuff. Or tinypenischan.org.

Because there are imageboards.

>>23-san, you are the imageboards.

That's why I've started using captchas to prevent your like. If only I was the textboards, or better: the firewall.

implementing one should be rather easy, however modern OCR should be much much better than such a simplistic attempt, and since one of the two words reCAPTCHA supplies is a word that two different OCR software gave different readings to (but even if you give the 'wrong' reading it can't know), an acceptable success rate should be possible using the state-of-the art propriety computer vision software.

I don't think you know how OCR works, or why Google created reCaptcha to begin with. HIBT?

By creating it, they unintentionally spurred the underground OCR research community.

They're afraid of what might happen if they spurred the underground AI research community instead.

No, Google completely understood that they were directly influencing the OCR research community, both legitimate and underground. reCaptcha is an incredibly elegant solution (the real definition to the word 'hack') to the problem of OCR.

Well, it would be if someone actually were stupid enough to fill out the to-be-OCR'd word. And I sure hope you guys don't do that.

Naturally my comprehension of OCR software as a postgraduate engineering student working in a computer vision project is no match for the genius who thinks Google created reCaptcha.

Well, it's great that you acquired the skill to look up things on Wikipedia during the course of your studies. Unfortunately, that doesn't really qualify you for doing anything but toy projects in Lisp, so I'd greatly appreciate if you went back to doing just that.

You're still trying way too hard.

Okay, I'll go away.
