I suppose OCR software might be able to do it. But I don't know much about how OCR software works.
m -- Marc Carter, PhD Associate Professor of Psychology Chair, Department of Behavioral and Health Sciences College of Arts & Sciences Baker University -- From: Rick Stevens [mailto:stevens.r...@gmail.com] Sent: Monday, January 28, 2013 11:14 AM To: Teaching in the Psychological Sciences (TIPS) Subject: [tips] computer perception I was talking about the use of distorted text for the Captcha screening device in my cognitive class. A computer-literate student pointed out that a web bot would not find text, but a jpeg file. This brought up the question of why the text needs to be distorted at all. The bot won't be seeing a screen (we assume). Could it be that a bot would encounter pictures and run an optical character reader program? If not, it brings up the question of why the text even needs to be distorted. Simply putting text in a picture file would seem to be a major barrier. I know spammers put a lot of effort into their jobs, but reading non-distorted text seems like a big task. The distorted text that a 5-year-old can read but a computer can't was brought up in the textbook, but I wondered if anyone knew how the web bots would actually try to read text in a picture.
