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!

Is JAVA related to Java?

No, wait, wrong question; you want to create an encoder - to create captchas - not a decoder - to solve captchas?

There's an idea: don't implement a captcha generator, implement E-braille.

Actually a captcha image to UNICODE would still be an encoder. That's what I want to do.

They do have a sound thing for disabled people. It's been online years ago.

No actually he is just trying to be 1337/prog/ haxorzz. Not that I care. He probably doesn't know shit past HS.

Yeah, they have a graphical button you can click on. I'm sure blind people can see that to click on it.

Actually, it's as easy as tab-tab-tab-tab-tab-tab-tab enter.

Yeah, that doesn't work so well when you can't see the picture to know what that button does. And it doesn't work at all if you do like some sites and make it a Flash button.

The image is likely to have a alt text setting. HTML audio readers often speak out alt text.

I give a minor fuck since they are the source of what I believe to be /prog/'s biggest ailment.

Sucks for you, but if we can't go back to the imageboards, we'll just camp here.

You can: just click in the right place on your Bookmarks Toolbar. You'll find it soon enough.


By the way, why are there two captcha threads?

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

>>22
Because there are 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.
