Are there handwriting recognition libraries available for the iPhone?

Question

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

Does anyone know of a good library for this?

Answer 1

You need to make some effort to compile, but Tesseract is a good solution.

For compilation see http://iphone.olipion.com/cross-compilation/tesseract-ocr . For an example application, see http://robertcarlsen.net/tag/tesseract

Answer 2

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

To limit OCR to numbers only, the Tesseract SDK provides a method of both blacklisting and whitelisting .

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

Using this method, you can restrict the recognition of only numbers.

Hope this helps.
