hello,
suppose i have an image, i have a text written with a specific font, and variable sizes.
How can i make my program read those letters or numbers?

Do a web search for "OCR" or "optical character recognition".
can you find me some sort of a source code for it? because i didnt find any.
the language is C Sharp
what i need is to read text from a bmp, all what i found was Hand Write text recognition, with neural network!
this is too advanced, i want something so simple and somehow accurate.

Doesn't exist.
This sounds like that one C# contest from a few months ago. I don't remember the site though. Maybe someone else does?

well i dont mean 100% accurate, i seek some 60% accuracy
I'd say approach the problem iteratively, first just get it to recognize a character, that is some sort of object surrounded by white-space, though by this definition 'i' is two characters so defining what exactly is a character might be a bit difficult. Anyway, when you've got this down, then try to get it to recognize a specific character, like 'A' and work from there. This is not an easy problem, so you should do as much research as you can on current systems. I would recommend going to your local college library and looking there, as this is an old problem and quite a few good papers on the subject probably haven't been posted online yet.
From Google:
- Character Recognition Overview
- Character Recognition by Feature Point Extraction
- ocrad
There seems to be a whole wealth of information on this subject. None of it looks too simple though. Good luck.
