In the last decade, data processing of vehicle license plates became a common subject of research with numerous methodologies proposed to address the problem. The license plate recognition technology converts image data from a camera into a character format that can be further processed and manipulated in a database in a specific application area. The characters on license plates are often unambiguous in identifying vehicles that are facilitated by optical character recognition methods. The aim
