Massive integration of information technologies into all aspects of modern life caused demand
for processing vehicles as conceptual resources in information systems. Because a standalone
information system without any data has no sense, there was also a need to transform
information about vehicles between the reality and information systems. This can be achieved
by a human agent, or by special intelligent equipment which is be able to recognize vehicles by
their number plates in a real environment and reflect it into conceptual resources. Because of
this, various recognition techniques have been developed and number plate recognition systems
are today used in various traffic and security applications, such as parking, access and border
control, or tracking of stolen cars.
