* You picture needs to have a strong contrast (black text, white background), and a good resolution.
* The OCR program scans the picture and uses glyph libraries to detect the characters. Those that are recognised recognized are transformed into the corresponding character.
* Dictionaries will be used to minimize errors. These compare the resulting words with existing words to determine the outcome and guess the words that were not fully recognized.
* Some programs recognize bold, italic or custom fonts size.
