OCR is trainable. That's why the abc files that are used in the examples match to the images used in these examples.

If you want to ocr true type fonts, you should create your own abc files with the OCR Training Interface that ships with the NI Vision Development Module.

so the question is how to convert true type fonts into .abc file? if such a convert exsit at all.

As far as I know there is no converter available.  That's why you will need to train the characters.

Not a bad idea! We should make one!

I gave the converter a shot. Hopefully this will help you out!

hello,

first of all thanks you all for your kind answers,it really helped.

i have few more questions:

1. i have train the charcters and created one .abc file which is gathered few true type fonts in it.

    the problem that accured was collision in the interpation,for example : between 8 to B or between l to 1.

   is there any way to improve the ocr accuracy so such collisioins wont occurre?

2. if i use few .abc files,how do i know which is the most ideal .abc file from all of them?

3. regarding to Alex T fonttoabc convertor- i have tried using this convertor with fonts im using (digital fonts) it created    an abc file,but the interpation wasn't good. any suggestions?

[Alex.T]

I opened up the .abc file it generated and... well...

That doesn't look too good.  I'll try to work some more on it!

[Alex.T]

Fixed! Please give it a shot!

And the result?
