Does any body have c++ source code to extract each text character from images and save this character in another subimage?
I'm working with PGM format

I think it will be easier to craft one's own text extractor than to try to fit an existing one, since such problems vary widely. For instance, an OCR task of reading newsprint will be very different from trying to grab electronic overlay text off of a Webcam.

i need same code using feedforward neural network, could you send me if you got it

As indicated in my last message in this thread, text extraction is a process which requires at least some tailoring to the problem at hand. The basic procedure is to identify "text" versus "background" pixels (for example through color), then extract individual glyphs (blobs of text pixels which are believed to represent single characters). The complication comes when, for instance, the image is noisy or text pixels cannot be well distinguished from the background.

predictor,
thanks for your care. honestly , my problem wasn't really extarction,i have some experience on that subject.real problem is that C++. my experience is on Matlab. i don't have any problem at algorithm. hence i just wanted to see a C++ source code to revise it.

Okay. Sorry, I can't help much there. I've used C++, but I found long ago that MATLAB is such an excellent fit for my programming needs, that I've abandoned just about everything else at this point. You might try searching on-line (I suggest Teoma, at www.teoma.com) for terms like:

"text extraction"
"C++ source"

Sub: Requesting guidance for our B.E final year project "Handwritten recognition using Neural network".

we are trying to convert handwritten document in to typed format.At the preliminary stage converting a single alphabet into binary value.we are using MATLAB 6.5.

We can convert typed Alphabet in "paint" into binary values.Using MATLAB could not get for our captured images.we capture images of an alphabet using webcamera.when we try to convert our capture images into binary value,we got all values as '1'.We can not load the captured images into the MATLAB.Only we can load reference images in MATLAB.

We also have thought of using light scanner arrangement for conversion of alphabet into binary values.Kindly give resources for conversion of handwritten alphabet into binary values.
