Are there any handwriting recognition libraries av

I am looking for a simple (preferably open source) handwriting recognition library for the iPhone/iPad. In my case, I'm only interested in recognizing numbers.

Does anyone know of a good library for this?

There are many libraries available for extracting text from images. You can check my answer

For restricting OCR to provide numbers only Tesseract SDK provides method as blacklist and whitelist characters

_tesseract->SetVariable("tessedit_char_whitelist", "0123456789");

Using this method you can restrict only numbers to be recognized.

Hope it helps.

You would have to make some efforts to compile but Tesseract is good solution.

For compiling it look http://iphone.olipion.com/cross-compilation/tesseract-ocr. For sample application see http://robertcarlsen.net/tag/tesseract
