Captchas are something I was seriously looking at when writing my thesis. Because I could never find any website which had good examples on how to decode them when I finished I wrote this article http://www.wausita.com/captcha/ http://www.wausita.com/captcha/ which shows from a very low level how to extract text from a picture and then read it. I post it here because anyone looking at this podcast may find it useful or interesting.
