I'm looking for some open optical character recognition (OCR) raw libraries that I can use to create a Java application that compares them. Anywhere I search I find just applications to OCR.
You can use
I have used tesseract (first option) and found that it is quite accurate (not 100% in my case). I directly used trained data for recognition. You can start with following code.
Tesseract tess = new Tesseract(); tess.setDatapath(tessDataPath); //Path to tessdata directory String text = tess.doOCR(new File(path)); // Path to input image System.out.println(text)
Hope this helps.
