How can I extract the Text from a GIF Image? Please help!
Hi!
I'm trying to code a testing application for my company's website which will try out all combinations of option buttons, list-box selections etc to make sure everything works out as expected. Unfortunately I've hit a brick wall when faced with the GIF "random security code generator" image. Could someone please detail how to decrpyt the text in the gif? Any API functions or similar that can be used to assist in this goal? The URL for the GIF pwd generator is available here (just temporarily until I can get past it with your help!): <www.nrma.com.au/PremiumEstimates/pepasswordgifgenerator? Many thanks in advance everyone! I really appreciate any light you can shed on this! |

Jas,
Isn't that the whole point of these; they virtually impossible to decypher by code/robots. NickHK "Jas" wrote in message ... Hi!

The "text" in a gif is not in text (string) form, it is a picture so there is
no real way to extract it except OCR - but these security images are designed to be resistant to attempts to read/convert them, and as Nick said the reason for that should be obvious. Frankly, if you or anyone were successful in finding a way to read the text with an automated process, you should tell your company that their security is not adequate. So the best result you should hope for is that your attempt will fail! "Jas" wrote: Hi!

I would not be at all surprised if this is not already possible, if not yet
then soon. Search terms: Cognitive-recognition, Pattern-recognition, ai, neural-networks Regards, Peter T "K Dales" wrote in message ...

OCR is definitely possible, and widely used - but the specific patterns used
to distort the letters to assure a human is reading the page (and typing in the text) are designed specifically to be unreadable by automated means. If not it would be very poor security - and that is my point. "Peter T" wrote: I would not be at all surprised if this is not already possible, if not yet then soon.

I wasn't trying to be contrary, but OCR is not quite what I had in mind.
This illustration was given to me by someone working on this topic: Imagine a crate of fish, a mixture of species packed un-arranged, with crushed ice partially covering them. A fisherman will easily identify each fish. But how to image process a picture of that crate, and supply a list of each partially visible fish. When this told to me about two years ago it was a challenge, being intensively worked on. I'll try and find out if it has been cracked! Regards, Peter T "K Dales" wrote in message ...

This makes interesting reading (see "Defeating CAPTCHAS").
