hi all..
i m working on my final year project,,its about CAPTCHA breaking...i.e. to show that captchas can be easily breakable....
for that following steps need to be followed:
1. firstly trace the position of characters in the input image.
2. then extract each character,,we can also say it as character segmentation..i.e. separating each character individually...
<<i have completed my project till dis step>>

now we have :
1. the segmented images...
2. a training set of images i.e. a set of images each representing an individual character.

what i want :
1. maintain a database in which 2 columns will be there... one representing the individual character i.e. from a to z...and second representing the value obtained after applying some function on the corresponding training image.
2. now after applying the same function on the segmented image which we have obtained in step 2,,we'll get their values also...now dese values will be compared in the database,,,nd the corresponding character'll be fetched.....
in this way v can get the text corressponding to that image...
what say guys.......

i just wanted to know which function shud i apply on the training set of images..........

..plz guys help me in this work... plz....

Please don't hijack old threads, and further do so posting the same thing more than once to multiple threads. I've deleted your other posts and moved this to its own thread.

This isn't exactly trivial, which is pretty much the point of captchas. What you're looking for is called OCR, or optical character recognition, and some googling will give you an idea of what you're getting yourself into.

That being said, please read the link in my signature on asking questions the smart way before you post again. For example, using text-message speak ("dese", "shud", and "plz" are not words) and poorly formatted sentences are great ways to make sure people don't help you. Also, requesting "fast response" via private email pretty much defeats the purposes of a public forum.
