How to read a charecters from and image?

[rails and rails only]

hi,

How to read a letters in one image. I want to read the alphabets
from that given image.

Please help me to solve this issue...

I do not see the relation with ruby, anyway, you need an OCR app or
library. Most are simple toys that don't work. Unless the text is of
good quality with a white background most fail.

Basically, you have two situations.

1- the characters in the image are generated from an identified computer font.

You can then easily try to match each character in the font, pixel per pixel.

2- otherwise, you will have to use some OCR algorithm to recognize the
character. Something that works well enough if there's noise is
neural-networks.

Stop that! He's probably looking to crack CAPTCHAs.

****, now this thread is gonna pop up every time some kiddie Googles how to
crack CAPTCHAs. Maybe the list admins could intervene?

So what? This is a non-trivial problem and no script kiddie is likely
to solve it anytime soon, whether in Ruby or in another language.

It is however trivial compared to the task of keeping living languages
from degradation

No, it's a trivial problem. Display the image on a webpage somewhere
and offer porn for a human if they decode it for you. They don't need
to know that the captcha is for a 3rd-party site.

It's automated. A porn site shows the captcha to access its pages, the
unsuspecting user posts the answer to get his smut, and a spambot behind
sends the answer to the original captcha, and posts its spam message in
the comments of the blog or registers its new email account to use in
spamming.

This being said, we're way off topic, here.

The weak-point in any security scheme is always human - but I think
that's the best use of the principle I've seen in a long time

Argument doesn't help. I know, I've tried.

That's when it's time for a hard re-boot
