Since the vehicle plates are based on different Country standards, they usually different in form, shape and material. Therefore the LPR systems are Country specific and are adapted to the Country where they are installed and used (in the above case - a UK installation). You can see a large collection of plates of different Countries - download some recognition demoes with the link at the bottom of this page.

Some plates have additional information written or attached to the plate, such as state identification (as in USA plates in upper smaller row), province initials (such as in China upper row), plate issue date lable (such as in USA plates), vehicle type (such as in Korea in an upper row), Country flag (as in Europe on the left side), and more. For most applications this additional information is not required (and is usually not identified due to the complexity, variation, quality and resolution).
