OCR and Neural Nets in JavaScript. A pretty amazing piece of JavaScript dropped yesterday and it’s going to take a little bit to digest it all.
It’s a GreaseMonkey script, written by ‘Shaun Friedle‘, that automatically solves captchas provided by the site Megaupload. There’s a demo online if you wish to give it a spin. Now, the captchas provided by the site aren’t very “hard” to solve (in fact, they’re downright bad – some examples are below): But there are many interesting parts here: The HTML 5 Canvas getImageData API is used to get at the pixel data from the Captcha image. If we crack open the source code we can see how it works. The first step is pretty clear: The captcha is copied into the canvas and then converted to grayscale. The canvas is then broken apart into three separate pixel matrices – each containing an individual character (this is quite easy to do – since each character is a separate color, they’re broken apart just based upon the different colors used).
