If you are talking about text reading, you have to distinguish between OCR (Optical Character Recognition) and OCV (Optical Character Verification). In an OCV application a known text will be verified. This means the quality of the text will be checked. In an OCR application the text to read is not known and the system determines the individual characters independently.

The system is independent of the used marking system and can read printed, lasered and needled fonts. The font must only be trained once to make it possible to read all texts and characters. The single or multiple reading by OCV or OCR can start after this one-time process. The learning process is very easy, because you only have to enter the printed text and select the area on the image where the text is located. Everything else (for example, single character search) is performed by the system automatically and autonomously.
