Should I Use OCR or OCV?

Most applications should use OCR because it provides more information than simply a success/failure. However, there
are times where you don't care about any additional information, but do require a bit better performance than OCR can
provide.

With OCR, the Sensor has no idea what to expect at each character position so, when it decodes an image for each
character pattern, it has to search the entire Font Library to find a character ID that matches.

For the OCV tool, on the other hand, each character position is filtered such that there are a finite number of character
variants associated with a single character ID.
