Apart from one blip (scepticism vs sccpticism) it outperforms me.

#12Not surprised. Not to be cavalier or anything, but I mean, even I was about to start a side-project to solve those things.
checkout captchasniper, was the best one a while ago.

#14As far as I know bots, even advanced ones, have an extremely hard time with dotted fonts. Just change the Captchas to use some really dotted or unique fonts where the letters are made up of smaller elements that don't connect. You can extend the life of Captchas for a few more years.

Eventually, the spammers will make a bot to analyze the distance between dots, group them into letters, and the race will be on to use other methods. I see this as a never ending virus/immunity battle. We're pretty much at the end of Captchas. Other methods like mouse movement, surfing time, scrolling, etc... can all be mimiced as well. Computers can or will be able to simulate humans very well, even our imperfections.

#15This is cool, but there's no indication from the article that it's novel, or that it's better than existing methods.
The article linked to 28 other different systems that have claimed to beat / demonstrated beating captchas at some point: http://www.karlgroves.com/2013/02/09/list-of-resources-break....
Without a performance comparison to existing methodologies on a benchmark dataset and precise details on the models, this is a neat marketing demo and nothing more.

#16Computers can simulate everything from visual character recognition to mouse movements and everything else we do online.
My prediction is that Google will one day enter the "Bot Recognition Market". They've got so much data on everyone and their browsing habits from Gmail, to Adsense, to Search results, to Google Analytics. Their cookies, browser, javascript, and ads follow you around all over the internet. They're the only company capable of putting all that data together and returning via API: "This user is a real person, we've analyzed 3 years of data from them, go ahead and let them sign up"
Or returning: "User is a bot, their IP has no purchases, no google account, no search requests, no adsense impressions, etc..."

#17> or let you know how many calories you’re about to eat by looking at your lunch.
I have previously told some people that this is the holy grail of dieting apps. The difference in ease of use between entering all of the items in your meal, one by one, and just taking a photo, would be a game changer. Of course, this is just a throwaway example in the article so they probably haven't done any of the work that would be required to make this a reality (aside from the vision processing, of course). I think it could be done with thousands of human raters estimating for you instead of a machine learning system, but I was skeptical of whether it could be profitable enough to justify it as a startup on a risk/reward basis. One day, maybe we'll see it though.

You might find these examples from LeNet interesting. They are examples of unusual styles of digits that the system correctly recognized, made of dashed lines, bubbles, and dots. Granted this system only recognized digits, but it's not exactly a stretch to jump to the character set typical of Captchas.

The hard part about this problem is getting the scale and thus volume of the objects right. How big is that bowl holding your cereal?
