I drew the box in the middle of the picture, despite what actual photo is (75% width / height of the original photo), 2 out of 15 times of trial, I get passed.

#23I have a background in breaking and designing CAPTCHAs at Microsoft Research; how is this un-OCRable?
If you're finding the objects automatically, you can write an algorithm to do that. If you're doing it manually, your corpus isn't going to be big enough, and I can just pay people to enumerate them.
Plus, for all of the examples I see on your page, you can just find objects of interest, which is fairly trivial, and that's probably going to be what you're looking for.

#24I think the site/service is pretty slick and well-made. It worked well for me -- I'd be curious to see what kinds of boxes these people failing were drawing (or whether it's just a browser issue for them or something).
These comments are all pretty negative, and I think the criticisms are mostly valid, but I don't think you've made a bad product (though it may need some tweaking, and captchas may be on their way out now for the reasons others have posted).
I just know that I've felt awful before when receiving similar comments to these others, and I would have liked someone to remind me: you made something pretty good, and it wasn't a stupid idea.

Hey Tyler,
You're right about certain images having easily distinguished objects-of-interest. In the future, running a routine to weed those easy ones out will stop any being solvable by bots. And also, as with any other captcha, paying other humans to validate themselves for you will always be an issue.
We validate users' inputs against a pool of manually-entered data. Because we collect a pair of annotations for each submission, one is used to verify the user, and the other is collected against an un-annotated image. As annotations are collected for new images, they are synthesized to expand the pool of annotated images.

#26this is cool - thanks for sharing. However - re-captcha is beautiful b/c it helps digitize goog books.

#27I was a robot four times out of five. This sheds a new light on my existence. On a serious tone, apart from a cool showcase of technology, do we REALLY need this? CAPTCHAs are the bane of everyone's internet time. Sometimes it works, sometimes it doesn't, sometimes I have to write strange unicode letters, when it fails I have to go back and re-input everything in the form,... And more importantly, the persons it's su…
Robot 5 times out of 5 for me.

#28Isn't object recognition in a not-distorted environment relatively easy? Click-and-drag is something UI automation does all the time, so that's not the hard part, either. A couple more thoughts: This requires a huge, human-written database (or it requires an algorithm ... and, oh wait, we already decided that if an algorithm can do it, then it's not really worth of being a captcha) Also, a few of the images, especial…
That's a good point, but we are a long way away from an automated general object recognition system. This discounts occasional outliers such as obvious objects which take up the whole page, or ones that are clearly visible against a gradient-less background (both of which can be pruned).
Currently, we are validating inputs from a human written database, which is continuously being expanded with new user inputs and new images. One image is used for validation, and the other is used for expanding the pool.

#29I think the cats vs dogs ones were a bit more entertaining.
Why is it that computers can drive cars on a highway, but they can't discern a human from a Nigerian spam bot?
The whole necessity should be embarrassing to programmers w/ access to a powerful server.
If they put CAPTCHA's on the Xcode Build command, the whole problem would be solved within the week.
Eat your own dogfood, developers.

#30Four out of five attempts... I'm a robot. I tried a couple more, with slightly better success, however one of those times I saw the same image in both panels. And then, it broke rather oddly: http://i.imgur.com/LwYtKe2.png (time approximately 00:45 BST, firefox 21.0, Win7)
